The main mind-altering (psychoactive) ingredient in marijuana is THC (delta-9-tetrahydrocannabinol), but more than 400 other chemicals also are in the plant. A marijuana “joint” (cigarette) is made from the dried particles of the plant. The amount of THC in the marijuana determines how strong its effects will be. The type of plant, the weather, the soil, the time of harvest, and other factors determine the strength of marijuana. The strength of today’s marijuana is as much as ten times greater than the marijuana used in the early 1970s. This more potent marijuana increases physical and mental effects and the possibility of health problems for the user. Hashish, or hash, is made by taking the resin from the leaves and flowers of the marijuana plant and pressing it into cakes or slabs. Hash is usually stronger than crude marijuana and may contain five to ten times as much THC. Research shows that the earlier people start using drugs, the more likely they are to go on to experiment with other drugs Driving experiments show that marijuana affects a wide range of skills needed for safe driving — thinking and reflexes are slowed, making it hard for drivers to respond to sudden, unexpected events. Also, a driver’s ability to “track” (stay in lane) through curves, to brake quickly, and to maintain speed and the proper distance between cars is affected. Research shows that these skills are impaired for at least 4-6 hours after smoking a single marijuana cigarette, long after the “high” is gone. If a person drinks alcohol, along with using marijuana, the risk of an accident greatly increases. Marijuana presents a definite danger on the road. Marijuana use increases the heart rate as much as 50 percent, depending on the amount of THC. It can cause chest pain in people who have a poor blood supply to the heart – and it produces these effects more rapidly than tobacco smoke does. Marijuana smoke has been found to contain more cancer-causing agents than is found in tobacco smoke. Young people who smoke marijuana heavily over long periods of time can become dull, slow moving, and inattentive. These “burned-out” users are sometimes so unaware of their surroundings that they do not respond when friends speak to them, and they do not realize they have a problem. http://www.well.com/user/woa/fspot.htm
