While THC can be used to medicate, THC is also used for recreational purposes.  Still, THC (delta-9-tetrahydrocannabinol) is in its own classification of substances: Cannabis. The reason THC is in its own class is that its reactions with the brain and body are unique. In other words, THC can’t be purely classified as a stimulant or a depressant because THC can produce both effects.

Still, the psychological element of addiction plays a role in how likely it is that you become addicted to THC. Sometimes, a psychological dependence on THC can be harder to overcome than physical dependency. However, most experts agree that the addictive potential of THC increases with the level and consistency of use.

THC dependence vs. addiction

THC dependence is not necessarily the same as THC addiction. Physical dependence on THC manifests as withdrawal symptoms when you stop taking THC. Withdrawal symptoms are one sure sign that you’ve become dependent on THC because the body needs the presence of THC to function normally.

That is, the main symptom of THC addiction is that you feel you need THC to self-medicate and deal with the stressors of life. However, the more you use THC, the harder it is to stop using it. Addiction can happen in those who start to abuse THC beyond medical reasons or who use THC to simply get high.

  1. My daughter started using CBD OIL AND THC prior to Pleomorphic sarcoma cancer, localised in the upper arm. She has now had the op and does not want radiation or chemo and is continuing with CBD OIL AND THC. I think she is overmedicating the THC. Changes in her behaviour

  2. I would like to know as after 9yr of use of constant canibis I do now suffer with many of the symptoms stated but memory problems etc will they reverse if I quit using the drug ?

  3. The question of physical addiction to THC must be studied taking into account two major contributing factors, namely genetics and personality.

    The word “addiction” is a misnomer as there is no anecdotal or scientific evidence demonstrating that a user must use ever-increasing amounts of THC to achieve the same effects. In addition, the THC user does not resort to violent crime or risky illegal behavior to obtain money for THC to stave off debilitating physical and mental withdrawal symptoms, as found for users of opiates, or a variety of other physically addictive or abuseable prescription medications.

    As for the claim that THC withdrawal can “cause panic attacks, anxiety, depression and aggression,” all of these behaviors are genetically predispositioned and so are not entirely attributed to the substance. After all, humans already possess cannabinoid receptors in the brain. Physical withdrawal is minor, temporary, and deleterious cognitive effects are reversible. Mental withdrawal symptoms are a function of individual personality and cannot be generalized to the population at large.

    Some individuals have no physical or mental THC withdrawal symptoms. Heroin addicts universally experience PAWS, or post-addictive withdrawal symptoms.

    Obviously there needs to be more scientific research on THC and addiction. Unfortunately, the DEA keeps cannabis as Schedule 1, equivalent to heroin, methamphetamine, and LSD. This misclassification prevents deeper research of THC by the orthodox medical and psychological community.

    THC, same as any other substance, has good and adverse effects. Same as for alcohol, sugar, caffeine, or salt. The effects vary along a spectrum of usage or withdrawal symptoms, but compared to many other things in today’s world, THC is a relatively benign chemical that does more good than bad.

  4. THC is not addictive to everyone I know someone who has smoked since they were 12 and cut it off completely when they turned 36 like its a slice of cold turkey therefore explain..

  5. Who believe the researchers those years when all the studies are sponsored or supported by various companies/governments to justify they decision. They will proof whet they want, history teach us that every day. Only reliable source are people who looking for help after noticing problem with using any substance. Do we see many addicted cannabis users around the world needing help or the number is not significant to be a problem. We all know about alcohol or tobacco world problem, millions of people looking for help because of those addictions. Cannabis is a illegal substance around the world, how can we trust research which is made behind closed door and only for “chosen” group of scientists. Lets educate people not punish them.

  6. Hello Sam. Researchers have found that regular marijuana smokers had less volume in the orbitofrontal gyri. This brain region is part of the orbitofrontal cortex, which is one of the primary areas within the reward system and is important for decision-making. Basically, the orbitofrontal cortex is a network of brain regions implicated in the addiction process. Psychological dependence is also when a person uses marijuana to be able to deal with stress or problems in life. When people start to believe they cannot do this whithout marijuana…wouldn’t you call it addiction if it were any other substance?!

  7. Hello D. Johns. As a former THC addict, and daily smoker, I would contest that anyone using THC to get high can become addicted to the sensation. While physical dependence on THC is less pronounced than opiates, for example, it is still a clinical manifestation. However, those using THC as a medicinal treatment without desire for euphoric effect may be able to avoid psychological dependence. But if many are honest, it’s the high that they are after.

  8. The possibility is .15%, and there are 4 active cannabinoids in Marijuana. Mainly two, THC and Cannabidiol, one produces the stimulant effect the other produces the sedative. This is dependent on how much of one or the other naturally exists in the strain. As for the reports on increasing addiction, this is false as you would have to have an addictive personality in the first place to even come close. There are many people who use Marijuana daily, multiple times, who can simply stop and not think about it again. It is not as addictive as this blog would lead one to believe, as well as the side effects only being present in those with severely addictive personalities. It is also known that the basic chemical makeup for cannabinoids is not at all vastly different from the “happy hormone” the human body produces naturally.
