Abraham Dweck 10/30/07 Dr. Elaine Olaoye PSYC 105 Marijuana Drug Paper Marijuana is the dried flowers, leaves and stems of the Cannabis sativa plant. The main active ingredient in marijuana is THC (delta 9 tetrhydrocannabinol). Marijuana can range from 1% THC to 8%. Hashish can be 7% to 14% THC and hash oil is up to 50% THC. THC is a fat soluble substance and can remain in the lungs and brain tissue for up to 3 weeks. There are over 200 nicknames for marijuana, including pot, herb, mary jane and chronic. Marijuana is usually smoked, using a pipe, a bong or by rolling a joint. Blunts are cigars that are emptied of tobacco and refilled with marijuana, sometimes in combination with other drugs. It can also be eaten in food, for example, by baking it in brownies. Smoking marijuana can relax a person and elevate their mood. This can be followed by drowsiness and sedation. Other effects include heightened sensory awareness, euphoria, altered perceptions and feeling hungry ("the munchies"). High concentrations of THC may produce a more hallucinogenic response.

simply not as strong as with most other drugs. The effect on the PNS results in changes to both voluntary and automatic motor controls. This, in effect, means that voluntary actions (such as muscle control) and automatic actions (such as gut, which is a smooth muscle control) are affected. The effect on these muscles, through the actions of THC, is one of relaxation. This is, in fact, what causes marijuana to be such an effective relaxant.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
