Those various stimuli (drug exposure, cue exposure and stress) modulate the neuronal activity in some cortical areas that control the ability to resist drug-taking and ultimately trigger the decision to use the substance88. Human laboratory studies have also tested medications that may reduce cannabis intake85. As an example, the CB1 receptor agonist nabilone reduces cannabis intake93, suggesting a possible therapeutic role for agonists in treating cannabis dependence.
Short-term effects of marijuana
Disulfiram is not a first-line treatment for cannabis use disorder alone. It is generally considered when other treatments have not been effective or when patients experience severe withdrawal symptoms. Baclofen is not a first-line treatment but may be an option in more advanced cases. Cannabis use disorder (CUD) occurs when a person becomes dependent on cannabis, leading to significant physical, psychological, and social challenges. Individuals with CUD often struggle to control their cannabis use, even when it negatively impacts their health, relationships, or responsibilities.

It’s crucial to seek help as soon as you develop signs of this condition. While individual people may report certain personal benefits, all of these factors make it difficult to come to drug addiction any firm conclusions. When you smoke marijuana, THC quickly passes from your lungs into your bloodstream. Your body absorbs THC more slowly if you eat or drink it — you typically experience the effects after 30 minutes to one hour. But it has approved certain purified substances derived from marijuana (analogs).
- Research also shows that the levels of THC in marijuana have been increasing over the past couple of decades.
- You can choose not to drive—and remind your friends and family to do the same—after using cannabis.
- Other signs of cannabis use disorder that may be noticeable to others include an unkempt appearance, withdrawal from social connections, and clear changes in mood or behavior.
What are the risks of marijuana?
The ‘high’ can produce a desire for repeated use, which in some users develops into CUD9. In addition, CUD occurs in approximately 1 in 10 regular users and as many as one-third of those who use daily1. Persons with CUD also have higher risks of poor mental health, psychoses and bronchitis10.
A review of studies performed in adolescents117 found some anatomical changes in fronto-parietal areas, but it was unclear whether these anatomical effects are directly cannabis use disorder related to cannabis use or to other factors such as depression. Altogether, it appears that anatomical effects of cannabis are more modest and much less than those created by regular alcohol exposure, which produces more substantial anatomical brain changes118. In humans, the most challenging aspect of addiction treatment is maintaining abstinence (that is, preventing relapse). Relapse has been modelled in animal studies using the self-administration paradigm and drug-seeking after abstinence88.
- NCCIH and the National Institutes of Health (NIH) provide tools to help you understand the basics and terminology of scientific research so you can make well-informed decisions about your health.
- Withdrawal is a distinct clinical syndrome recognized in frequent users who suddenly reduce or stop cannabis intake.
- An individual’s risk of CUD can in addition be influenced by cultural norms, values, rules and the price, availability and supply of drugs, and drug policy, legislation, prosecution, prevention and access to treatment10,166,167.
- But researchers are still learning about these, especially long-term effects.
Approximately 9.9% of individuals who reported cannabis use in the past year were daily or near-daily users1. Cannabis use disorder (CUD) is broadly defined as the inability to stop consuming cannabis even when it is causing physical or psychological harm4,5. Global data on CUD are incomplete, but according to the most recent global estimate 22.1 million persons met diagnostic criteria for CUD in 2016 (289.7 cases per 100,000 people)6.
