Medical marijuana  refers to the use of parts of the herb marijuana as a  physician-recommended form of medicine or herbal therapy, or to  synthetic forms of specific cannabinoids such as THC as a  physician-recommended form of medicine. The Cannabis plant from  which the cannabis drug is derived has a long history of medicinal use,  with evidence dating back to 2,737 BCE. Industrialist pressure groups  plying government with their interests, such as the replacement of nylon  rope over hemp rope, lead to the criminalisation of cannabis in America  in 1938. Synthetic cannabinoids such as Marinol and Cesamet are  available as prescription drugs in some countries.
  Studies,  some of which are disputed, have shown that medical marijuana has  effects in the treatment of nausea, vomiting, premenstrual syndrome,  insomnia, lack of appetite, spasticity, neurogenic pain, movement  disorders, asthma, many types of cancer, glaucoma, alcohol abuse,  bipolar disorder, depression, epilepsy, Alzheimer's disease,  inflammatory bowel disease, migraines, fibromyalgia, collagen-induced  arthritis, and many others. It relieves some symptoms of multiple sclerosis, AIDS, chemotherapy, and spinal cord injuries.
  Before  we go further, let us defined the most basic definition of Marijuana is  a green, brown, or gray mixture  of dried, shredded leaves, stems,  seeds, and flowers of the hemp plant.  You may hear marijuana called by  street names such as pot, herb, weed,  grass, boom, Mary Jane, gangster,  or chronic. There are more than 200  slang terms for marijuana.All  forms of marijuana are mind-altering. In other words, they change  how  the brain works. They all contain THC  (delta-9-tetrahydrocannabinol),  the main active chemical in marijuana.  They also contain more than 400  other chemicals. Marijuana's effects on  the user depend on the  strength or potency of the THC it contains.  The potency of marijuana  has increased since the 1970s but has been about the same since the  mid-1980s.
Marijuana addiction has clear signs and  indicators                and this page will discuss this in. Marijuana  addiction is                simply an uncontrollable urge to possess and  use the drug. Those                with marijuana addiction are not  able to stop using the drug even                if they wish. Often a  person with marijuana addiction will make                continuous  excuses about why now is not a good time to stop using                 the drug. Such people are not alone. Marijuana addiction is a disease                 that affects millions of people every year. There is a good  reason why admission to rehabilitation                facilities has  doubled for marijuana addiction. The potency of the                drug  continues to get more powerful and studies show that teens                 can get a hold of marijuana often easier than alcohol. Even those                 who seek treatment for drugs that are perceived has "harder"                 like heroin or cocaine will often acknowledge that  marijuana is                their primary drug of choice.
