Marijuana Addiction and Effects
Learn about short-term and long-term effects of marijuana and how to get help.
Marijuana (also known as weed, pot, grass, and Mary Jane) consists of various parts of the hemp plant known as Cannabis sativa. The hemp plant contains a mind-altering chemical known as THC. It can be smoked, inhaled with a vaporizer, or mixed into foods or liquids. Marijuana is mostly used recreationally and is known to induce a relaxed state. Heavy marijuana users report lower life satisfaction, poorer mental and physical health, more relationship problems, and less success in life and school. This can develop into a marijuana addiction.
Marijuana effects
- Short-term effects: altered senses, increased heart rate, impaired movement, mood changes, memory and problem-solving difficulties.
- Long-term effects: depression, anxiety, suicidal thoughts, breathing problems, paranoia, hallucinations.
Medicinal benefits
The scientific data for marijuana as a treatment for many medical conditions is ongoing. The use of marijuana for some health issues such as chronic pain, multiple sclerosis, and glaucoma is being studied. Consideration is also being given to the use of marijuana to treat many other disorders and diseases.
Youth and marijuana use
Adolescents and young people who recreationally or habitually use marijuana could suffer damage in brain functions, particularly with memory, thinking, and learning. The results may be long-term or even permanent. Because their brains are still developing, the risk factors are much higher.
Addiction occurs in 9% of all marijuana users, jumping to 17% in adolescents. Attempting to quit can produce withdrawal symptoms of irritability, difficulty sleeping, anxiety, and decrease in appetite.
Treatment
While there is currently no medication available to treat a marijuana addiction, there are multiple therapies available. Cognitive behavioral therapy can help users increase self-control, stop altogether, and address the problems caused by heavy drug use. Motivational enhancement therapy encourages users to create internally motivated changes to counter drug use. If you or someone you know needs help, here are some steps to take:
- Seek help – Be open with your doctor or counselor about your marijuana habits. They can help you personalize a plan for change.
- Hydrate – Be sure to drink plenty of water. Reduce your caffeine intake until any altered sleep patterns normalize.
- Exercise – Physical activity helps alleviate depressive symptoms and promotes good health. Exercise also aids your body’s healing process.
- Avoid triggers – Stay away from places and people who encourage your marijuana use. Surround yourself with those who respect your choice to stop using.
- Find support – There are a variety of 12- step programs and support groups available to help you on your journey.
KEEP IN MIND
Marijuana addiction, along with any substance use issue, doesn’t need to write your life story. Be courageous and seek help for a healthy, new start on life. There are ample resources available to live an addiction-free life.
