Tolerance, Dependence and Chronic use of Marijuana
Casual and recreational use of marijuana does not cause physical dependence like narcotics, alcohol, barbiturates and nicotine. However, withdrawal symptoms have been observed among individuals who repeatedly are exposed to high, frequent doses.
Tolerance to cannabis is the result of receptor adaptation in the brain. This accounts for frequent users, requiring high quantities to produce less effect, while individuals who are unaccustomed to its effects are much more susceptible to its dream like state with much lower doses.
Chronic, habitual use of marijuana will cause bronchial inflammation. Bronchial inflammation impairs the gaseous exchange in the lungs and is caused by the persistent and repetitive pounding on its epithelial lining. The prolonged inhalation of gas particles and the inflammation that follows is the reason for the damage, not the THC molecule.
The chronic high dose use of Cannabis results in a motivational syndrome, a disorder characterized by apathy, impaired judgment, and loss of interest in appearance. There is also the possibility that chronic use can lower fertility rate and lower sperm counts.
Heavy marijuana use impairs motor coordination and short-term memory.
Teenagers who use marijuana regularly are less motivated to exercise. Since this program is entirely based on exercise, any thing that detracts from exercise can never be recommended
Marijuana is one of earliest of medicinal therapies. Marijuana, for medicinal use in the United States is legal in eleven states and more have legislation pending that will legalize it. At issue is whether, the botanical ingredients of marijuana should be available to people with serious illness or not. The real question is whether or not marijuana use will remain limited when it become legal.
Marijuana is a divisive issue because laws have made it so. Marijuana is illegal under the Controlled Substance Act, which classified it as a Schedule I, substance along with heroin, LSD and morphine, peyote and mescaline. They are all considered drugs with a high potential for abuse and no accepted medical use. They are differentiated from Schedule II substances by the accepted medical use of the latter not because of the potential for abuse. Both Schedule I and II drugs induce addiction.
These drugs, with the exception of marijuana, produce their psychoactive effects through the activity of nitrogen containing alkaloids. These alkaloids affect the chemistry of nerve endings by mimicking, blocking, or prolonging nerve transmissions.
Proponents of the medicinal use of marijuana and others whose effort to reform the U.S. government’s war on drugs, have pointed to the beneficial effects of smoking marijuana as justification for its legalization. Other marijuana advocates hurt their cause by arguing that certain diseases (epilepsy and multiple sclerosis) can be treated with it.
The placebo effect experienced by patients who believe in the power of marijuana to heal is enough to support its legalization.
In 2012, Colorado and Washington voted to legalize marijuana for recreational use. Stay tuned!
