Quick answer
Ohio legalized adult-use cannabis in 2023, with sales starting in August 2024 for adults 21 and up. Legal does not mean risk-free: cannabis use disorder is real, and cannabinoid hyperemesis syndrome can send heavy users to the ER. Within 30 miles of Chillicothe, 12 programs offer contingency management. Here is how treatment works.
Is marijuana addictive?
It depends on how often and how early someone uses. Many people use cannabis without developing a problem, but frequent use can tip into cannabis use disorder - a pattern of use that causes real impairment or distress - and federal health advisers report that the number of people with past-year CUD has grown alongside higher-potency products and wider legalization. Starting before age 18 raises the risk, and withdrawal is real: irritability, anxiety, sleep trouble, and cravings that peak in the first week after quitting. If cannabis is costing you work, relationships, or health, that is the signal to get a real assessment.

What changed in Ohio - and what did not
Ohio voters approved adult-use cannabis in November 2023, and licensed non-medical sales began August 6, 2024, according to the Ohio Department of Commerce. Medical cannabis has been legal since 2016, and medical sales began in 2019. Under Ohio Revised Code 3780.36, adults 21 and older may possess up to 2.5 ounces of cannabis and 15 grams of extract, and grow up to six plants per person, capped at 12 per household. Adult-use purchases carry a 10% excise tax on top of sales tax; registered medical patients are exempt from the excise tax, per the Ohio Department of Taxation.
What legalization did not change is that cannabis can still cause a substance use disorder, and that treatment for it exists. The rules around possession are about the law, not about risk.
Cannabis use disorder, in plain terms
A 2024 federal advisory on cannabis use disorder reports that in 2024 an estimated 20.6 million people ages 12 and older in the U.S. had past-year CUD, up from 16.7 million in 2021, and links the rise to higher-potency products, expanded legalization, and lower perceived harm. NIDA notes that THC changes mood, thought, and perception, and that frequent use can affect memory, attention, and mental health.
Signs that cannabis has moved past casual use include using more than you intend, failed attempts to cut back, spending a lot of time obtaining or recovering from use, cravings, and continuing to use despite problems at work, school, or home. None of that is a moral failing - it is the definition of a treatable condition.
Cannabinoid hyperemesis syndrome (CHS)
Heavy, long-term cannabis use can cause a less-known problem: cannabinoid hyperemesis syndrome, or CHS - repeated episodes of severe nausea, vomiting, and abdominal pain. A systematic review of CHS treatment describes a hallmark behavior of compulsive hot showers or baths for relief, and notes that standard anti-nausea drugs often do not help. The only reliable cure is stopping cannabis - in the reviewed studies, the large majority of people who quit saw symptoms resolve, while resuming use brought them back. If vomiting is severe or you cannot keep fluids down, get medical care the same day.
What treatment looks like
There is no FDA-approved medication for cannabis use disorder, so treatment is behavioral. The approaches with the strongest evidence, per the federal advisory, are:
- Cognitive behavioral therapy (CBT) - recognizing the triggers, moods, and routines that drive use and building different responses.
- Motivational enhancement therapy (MET) - a short, non-judgmental approach that helps build your own reasons to change.
- Contingency management (CM) - small, non-cash rewards for negative drug tests. This works especially well for people who struggle to stay engaged early on.
A SAMHSA locator search 30 miles out from Chillicothe lists 16 substance use programs, and 12 of them report offering contingency management. The network also includes 10 intensive outpatient programs, 6 programs with residential beds, and 3 offering medical detox. The Paint Valley ADAMH Board (394 Chestnut Street, Chillicothe; 740-773-2383) funds local addiction services across Ross, Fayette, Highland, Pickaway, and Pike counties and can help if cost is the barrier.
