    According to the National Institute on Drug Abuse, marijuana is a Schedule 1 substance, which means that it has no medicinal purpose and has a high risk for abuse. Although marijuana is not federally legalized or approved by the FDA, 20 states (including Hawaii and Washington D.C.) have already legalized medical marijuana, and two of those states (Colorado and Washington) have already legalized marijuana for adult recreational purposes. When marijuana is ingested or smoked, THC (Tetrahydrocannabinol) a chemical naturally found in marijuana, targets neural receptors in the brain giving users a “high.” Altered perceptions and mood, impaired coordination, difficulty with thinking and problem solving, and disrupted learning and memory are some of the effects that marijuana users may feel. Long term effects of heavy marijuana use include: respiratory problems (daily cough and phlegm production, frequent acute chest illness, and increased risk of lung infections), increased heart rate by 10-100 percent, and mental health problems, such as depression, anxiety, suicidal thoughts among adolescents, and personality disturbances, including a lack of motivation to engage in typically rewarding activities. Studies have also shown marijuana to be psychologically addictive.…

    Unlike many other illicit drugs marijuana is not considered a stimulant or a depressant. While stimulants and depressants (such as cocaine, methamphetamine, alcohol, and heroin) interact with either the serotonin, dopamine or GABA nerve receptors in the brain, the chemicals found in marijuana react in a completely different manner. They react with CB1 and CB2, a set of nerve receptors unique to the chemicals in marijuana, and to a naturally occurring neurotransmitter called anandamide (Caulkins, Hawken, Kilmer, & Kleiman, 2012). An increase in appetite, a greater appreciation for humor and a boost in creativity are all possible effects of a marijuana high due to the unique chemical reactions within the brain. However, not all marijuana highs can be enjoyable, as high doses can cause anxiety and paranoia.…

    Cannabis sativa is a dioecious, sexually reproducing plant. This means that plants are either male or female, male plants contain a stamen but not a carpel and female plants contain a carpel but not a stamen. This ensures cross pollination will take place. In the wild this type of reproduction would mean that there was more variation between individuals, as plants are not just ‘clones’ of each other (because of self pollination which results in ‘a’ sexual reproduction). This variation would mean that the population would be more likely to survive if there was a change in the environment as there are a lot of…
