​Marijuana affects each person differently depending on their biology, the plant’s potency, previous experience with drugs, the way a person uses the drug, and the use of alcohol or other drugs at the same time. Some people feel nothing while others feel relaxed or high. Others suddenly get anxious and paranoid (the link between marijuana and schizophrenia was blogged by me earlier). We are still learning about how marijuana affects the brain and how long the effects will last.
 
Regular marijuana use has also been linked to memory and relationship problems, poorer mental and physical health and less career success. Short-term effects include learning attention and memory problems, poor coordination, increased heart rate, anxiety and paranoia; as well as sleep problems. Long terms effects include becoming addicted to marijuana; long-term learning and memory problems; risk of chronic cough or bronchitis; risk of schizophrenia (as already discussed in a previous blog).
