Marijuana acts on the cannabinoid receptors in the brain kicking off a series of cellular reactions that lead to the “high” experience.

The highest density of cannabinoid receptors are found in parts of the brain that influence pleasure, memory thoughts, concentration, sensory, time perception, and coordinated movements.

Marijuana can cause distorted perceptions, impaired coordination, difficulty in thinking and problem solving, and problems with learning and memory.

Long term effects include: addiction, irritability, sleeplessness, decreased appetite, anxiety, respiratory illnesses, and drug craving.

Chronic use has shown an increased rate of anxiety , depression, suicidal ideation, and schizophrenia.

Withdrawal symptoms begin 1 day after abstinence peaking at 2-3 days and lasting 1-2 weeks.

The chance for a heart attack quadruples in the first hour after smoking with an increase in blood pressure and heart rate.
