Evidence-based CBT, motivational enhancement, and dual diagnosis care under one clinical team
Radix Recovery provides evidence-based marijuana addiction treatment in Cedar Rapids, Iowa, built on cognitive behavioral therapy, motivational enhancement therapy, and integrated dual diagnosis care, with residential and outpatient pathways under one clinical team. Marijuana addiction is real: the National Institute on Drug Abuse reports that roughly 3 in 10 people who use marijuana have some degree of cannabis use disorder. If weed has stopped being a choice and started running your life, we can typically arrange admission within 24 hours.

Yes. We hear the skepticism every week: “It’s just weed.” “It’s legal now.” “It’s natural.” None of that changes the brain science. The National Institute on Drug Abuse (NIDA) reports that marijuana use can lead to cannabis use disorder, and that roughly 3 in 10 people who use marijuana have some degree of it (NIDA). Addiction is the severe form of that disorder: you keep using despite real consequences, you have tried to cut back and could not, and your brain and body push back hard when you stop.
THC, the main psychoactive compound in marijuana, acts on the brain’s endocannabinoid system, the network that helps regulate mood, sleep, appetite, and stress. With regular use, the brain reduces its own endocannabinoid activity to compensate. That is tolerance and dependence in plain terms, and it is why daily users feel flat, irritable, and sleepless without weed. The dependence is physical, the coping pattern is psychological, and addiction treatment has to address both.
One more thing has changed, and it matters: today’s marijuana is not the marijuana of decades past.
“It’s the same weed it’s always been.”
NIDA reports that the average THC content of cannabis has climbed sharply over recent decades, and modern concentrates, dabs, and vape cartridges can deliver THC concentrations far above traditional plant material. Higher potency and more frequent exposure are associated with greater risk of dependence, cannabis use disorder, and mental health effects. Someone vaping high-THC oil all day is running a very different experiment on their brain than a previous generation ever did.
“It’s legal now, so how bad can it be?”
Alcohol is legal too, and nobody argues it cannot be addictive. Legal status, medical cards, and dispensary packaging do not change how THC interacts with the brain. The same is true for medical marijuana: daily high-THC use can still produce tolerance, dependence, and cannabis use disorder regardless of why you started.
“Honestly, it’s the only thing that calms me down.”
NIDA links regular marijuana use, especially high-potency use that starts young, to anxiety, depression, and an increased risk of psychosis in vulnerable individuals. Many people also use weed to self-medicate those same conditions, building a cycle that gets harder to see from inside. Our dual diagnosis treatment program addresses the cannabis use and the mental health condition together.
“You can’t actually go through withdrawal from weed.”
Cannabis withdrawal is a recognized clinical syndrome. NIDA documents irritability, sleep difficulty, decreased appetite, cravings, restlessness, and anxiety in people who stop after regular use. It is rarely dangerous, but it is uncomfortable enough to drive most quit attempts back to use within days, which is exactly what structured treatment prevents.

A quick note on names: this page covers marijuana, weed, cannabis, and THC products, which are all the same plant-derived drug. It does not cover K2 or Spice, which are synthetic compounds with different and more dangerous pharmacology; we treat those separately on our synthetic cannabinoid page.
If you have ever stopped for a few days and felt like a different, angrier, sleepless version of yourself, you have already met cannabis withdrawal. It is not dangerous the way alcohol or benzodiazepine withdrawal can be, but it is real, it is documented by NIDA, and it is the single biggest reason “I’ll just stop on my own” attempts collapse in the first week. Daily users of high-potency THC products typically experience the strongest version of the timeline below. Our clinical team supports you through every phase with structure, sleep-focused care, and supportive medical attention for symptoms as needed.
Within 24 to 72 hours of the last use, irritability, restlessness, anxiety, and cravings surface. Appetite drops, sleep gets shallow, and the urge to “take the edge off” with one more session gets loud. This is where most home quit attempts quietly end. In treatment, this is when structure, accountability, and a plan replace willpower.
Symptoms reach maximum intensity: anger and irritability, insomnia and vivid or disturbing dreams, anxiety, low mood, headaches, sweating and chills, stomach discomfort, and strong cravings. Friends and family often notice the mood change before you do. Our clinicians focus heavily on sleep support and emotional regulation skills through this stretch, because exhausted and irritable is exactly the state that drives relapse.
Mood levels out, appetite returns, and the constant edge softens. Most acute symptoms largely resolve within 1 to 2 weeks. This is also when the deeper work starts: without weed managing your stress, boredom, and emotions, therapy gives you the skills that were never built while THC was doing the job.
Disrupted sleep, vivid dreams, and intermittent waves of craving can linger for weeks to a few months, especially after years of daily high-THC use while the endocannabinoid system recalibrates. These are the months where ongoing outpatient care, relapse prevention skills, and our alumni community keep one bad night from becoming a return to daily use.

Call us, any hour
Arrive and assess
On arrival, our medical team completes a full assessment: use history, fentanyl exposure, withdrawal severity, co-occurring mental health screening, and lab work. You meet your nurse before you unpack.
Begin medication
Once withdrawal is clearly established, our physicians begin Suboxone induction, timed carefully to avoid precipitated withdrawal, plus comfort medications for nausea, sleep, and anxiety.
Stabilize and rest
Your first night is about safety and relief. Our 24/7 nursing team checks on you through the night, monitors your vitals, and adjusts your protocol so withdrawal stays managed while your body begins to recover.
One confidential call replaces another failed solo attempt with an actual plan. Our admissions team is ready right now.
Here is an honest clinical fact most rehab websites bury: there is currently no FDA-approved medication for cannabis use disorder. That makes the quality of the therapy the whole ballgame. NIDA identifies cognitive behavioral therapy, motivational enhancement therapy, and contingency management as the behavioral treatments with the strongest evidence for cannabis use disorder (NIDA), and those three approaches form the backbone of our program, delivered by licensed clinicians. Our physicians provide supportive medical care for withdrawal symptoms like insomnia and anxiety, and where a co-occurring condition like depression warrants its own medication, our team manages that as part of one integrated plan.
Cognitive behavioral therapy
CBT maps the chain between your triggers, thoughts, and use: the after-work ritual, the can’t-sleep-without-it loop, the anxiety spike that sends you to the vape pen. Then it builds and rehearses replacement skills for each link. For long-term daily users, CBT essentially teaches your brain the stress regulation and sleep habits that THC has been outsourcing for years.
Motivational enhancement therapy
Almost everyone arrives ambivalent: part of you wants to quit, part of you insists weed is the only thing keeping you sane. MET does not lecture that second voice. It works with your own values and goals, the job, the relationship, the fog you want lifted, until the decision to change is genuinely yours. Ambivalence resolved beats compliance every time.
Contingency management
CM provides structured, tangible rewards for verified abstinence in early recovery. It sounds simple, and the research support is strong: consistent positive reinforcement helps bridge the months before the natural rewards of recovery, better sleep, clearer thinking, money in your account, fully arrive.
Anxiety, depression, ADHD, and trauma show up constantly alongside cannabis use disorder, both as causes and as consequences of heavy THC use. We screen everyone and treat both conditions with one team and one plan, including psychiatric care when indicated, rather than referring you across town. If cannabis-induced anxiety or low mood is part of your story, this is where it gets addressed.

Marijuana addiction treatment is not one-size-fits-all, and it usually does not start in a detox bed. Because cannabis withdrawal is uncomfortable rather than medically dangerous for most people, the typical entry point is our intensive outpatient program, where you build skills while keeping your job and home life. Heavy all-day use, a string of failed quit attempts, an environment soaked in triggers, or serious co-occurring mental health needs are the signals that residential immersion will serve you better. Either way, every level below runs under one clinical team in Cedar Rapids, so stepping up or down never means starting over with strangers.
All six levels of care — one campus in Cedar Rapids, one clinical team.
Most clinical → Independent
Rarely required for cannabis alone, but available when marijuana use is combined with alcohol, benzodiazepines, or opioids that need supervised withdrawal.
Full immersion in our restored Higley Mansion facility for heavy daily use, repeated relapse, or significant dual diagnosis needs. Our residents get structured days, daily therapy, and 24/7 support.
4 to 8 hours of clinical programming daily with off-site living, a strong middle path when outpatient is not enough structure.
9 to 20 hours per week, built around work and family. This is where most of our Radix community members with cannabis use disorder begin: CBT, MET, group work, and real-life skill practice between sessions.
Weekly therapy and relapse prevention through the months when sleep disruption and cravings still flare.
Long-term connection to our alumni community, recovery events, and a team that picks up the phone if you ever wobble.
Our facility sits in Cedar Rapids, and people come to us from every corner of the state. For daily cannabis use, distance helps: stepping away from the dispensary run, the smoking circle, and the dealer’s number gives treatment room to work. Our admissions team coordinates travel logistics, family communication, and insurance for every Iowa community we serve, whether you are commuting to IOP or admitting to residential care.

Yes. The National Institute on Drug Abuse reports that marijuana use can lead to cannabis use disorder, and that roughly 3 in 10 people who use marijuana have some degree of the disorder. Addiction is the severe end of that spectrum: continued use despite real consequences, failed attempts to cut back, and withdrawal symptoms when you stop. The fact that marijuana is legal in many states and feels milder than other drugs does not change the brain science.
Both. Regular THC use downregulates the brain’s own endocannabinoid receptors, which creates tolerance and physical dependence. When you stop, NIDA documents a recognized withdrawal syndrome: irritability, sleep difficulty, decreased appetite, cravings, restlessness, and anxiety, typically peaking within the first week. The psychological side, using weed to cope with stress, boredom, or low mood, is just as real and is the main focus of behavioral treatment.
Cannabis withdrawal usually begins within 24 to 72 hours of stopping, peaks during the first week with irritability, insomnia, anxiety, and appetite changes, and largely subsides over 1 to 2 weeks. Sleep disturbance, vivid dreams, and intermittent cravings can linger for weeks to a few months, especially for daily users of high-potency THC products. Structured treatment and sleep-focused clinical support make this stretch far more manageable than quitting alone.
It can be. The THC in a medical marijuana product acts on the same brain receptors as THC from any other source, so daily use can still produce tolerance, dependence, and cannabis use disorder. A medical card does not make the compound risk-free, particularly with high-THC formulations used every day. If you started with a card and now find you cannot function or sleep without it, that pattern is worth a confidential conversation with our clinical team.
Potency. NIDA reports that the average THC content of cannabis has risen sharply over recent decades, and modern concentrates, dab products, and vape cartridges can deliver far higher THC concentrations than the plant material of past generations. Higher and more frequent THC exposure is associated with greater risk of dependence, cannabis use disorder, and mental health effects, which is why someone who ‘only smokes weed’ can still end up needing real treatment.
There is currently no FDA-approved medication for cannabis use disorder, so our treatment is behavioral-therapy-led. We use cognitive behavioral therapy to rebuild coping skills, motivational enhancement therapy to resolve ambivalence about quitting, and contingency management to reinforce early abstinence, the three approaches NIDA identifies as most promising for cannabis use disorder. Our physicians also provide supportive care for withdrawal symptoms like insomnia and anxiety, and we treat any co-occurring mental health conditions at the same time.
Yes, especially with heavy use of high-potency THC. NIDA reports associations between regular marijuana use and anxiety, depression, and worsened symptoms in people with existing mental health conditions, and links high-THC use, particularly when started young, to an increased risk of psychosis in vulnerable individuals. Many people also use weed to self-medicate anxiety or depression, which builds a cycle. Our integrated dual diagnosis program treats the cannabis use and the mental health condition together, with one team and one plan.
It depends on your pattern. Some people taper off successfully on their own. If you have tried to quit and keep going back, use daily or near-daily, rely on weed to sleep or to manage anxiety, or have a co-occurring mental health condition, structured treatment dramatically improves your odds. Most of our Radix community members with cannabis use disorder start in our intensive outpatient program, while residential care fits heavy daily use, repeated failed attempts, or significant dual diagnosis needs.
It depends on the level of care that fits your situation. Intensive outpatient typically runs about 12 weeks at 3 days per week. Residential treatment follows 30, 60, or 90-day pathways for heavier use or dual diagnosis needs. Many people step down through more than one level. Our clinical team builds a recommendation during your confidential assessment, and length is adjusted to your progress, not a fixed calendar.
In most cases, yes. Cannabis use disorder is a recognized substance use disorder, and treatment is an essential health benefit under federal parity law. We are in-network with Wellmark Blue Cross Blue Shield, TriWest Healthcare Alliance, Midlands Choice, Cigna Healthcare, Health Choice, and Medical Associates, and we work with many other plans.
