Like any medication, marijuana can have potential benefits and potential side effects. Short-term effects of marijuana occur because THC rapidly moves into the blood stream and acts on cannabinoid receptors, leading to a “high” for users.
Cannabinoid receptors are found in parts of the brain that influence concentration, mood, sensory and time perception, memory, pleasure, and coordination. These effects of marijuana normally cease shortly after use.
Long-term effects of marijuana can lead to difficulties with learning, motivation, and concentration. Long term side effects from smoking marijuana can lead to respiratory and circulatory problems. Marijuana use has been associated with mental health problems including anxiety, depression, and schizophrenia.
Using marijuana while pregnant must be avoided as children born to mothers using marijuana have been shown to have learning and problem-solving difficulties as well as potentially other health problems.
The potential for dependency, addiction, and withdrawal can occur after marijuana use, even when it is used as a short-term medication. Marijuana withdrawal can include: anxiety, decreased appetite, irritability, aggression, and difficulty sleeping. Withdrawal symptoms peak after three to six days and will subside within 1-3 weeks.
