Short-term effects
Mental effects of short-term (acute) marijuana use can include:
loss of short-term memory,
impaired ability to focus and pay attention,
impaired ability to concentrate and learn,
loss of motor coordination,
poor reaction time,
impaired judgement and ability to think,
sleepiness,
dizziness,
fatigue,
psychotic episodes,
mild paranoia, anxiety, and fear,
panic attacks,
perceptual distortions (visual, auditory),
severe agitation,
disorientation, and
confusion.
Long-term effects
THC is the substance that is responsible for most of the effects of marijuana. THC levels in marijuana today are much higher than they have been in the past. Some of the harmful effects of marijuana can last for hours, days, weeks, months and even years after last use. Regular long-term marijuana use can:
harm concentration,
cause loss of memory,
harm the ability to think and make decisions, and
decrease IQ.
The risks of experiencing these harmful effects increase in those who start using marijuana regularly as a teenager. Youth are especially vulnerable to the health effects of marijuana use, including harmful effects on mental functioning, and psychosis and schizophrenia.
Some people who use marijuana may be at higher risk of developing mental illnesses like psychosis or schizophrenia, including those who:
have a personal or family history of psychosis and/or schizophrenia,
start using marijuana young,
use marijuana daily or a few times a week, and
use marijuana for months or years.
Even if a marijuana user does not develop a mental disorder, the drug's effects can ruin school and work performance.
Marijuana addiction
Marijuana addiction can have a number of harmful consequences on health, but it can also harm one's social, scholastic, professional and financial future.
Marijuana use that begins early and continues over time can lead to changes in the brain and body that contribute to developing an addiction to marijuana. Once an addiction has developed it may be very hard to stop using marijuana, even though it interferes with daily life.
Marijuana use that begins early in adolescence, that is frequent and that continues over time can lead to addiction. It is estimated that 1 in 9 marijuana users will develop an addiction to marijuana.
This number rises to about 17% for people who started using marijuana as a teenager. If a user smokes marijuana daily, the risk goes up to between 25-50%.
