Proposition 215 and You

Proposition 215 was created to protect the seriously and terminally ill. It does not include recreational users of marijuana who feel they get the same "medical" benefits. It does not even apply to terminally ill patients who fail to get their physicians' approval. Proposition 215 allows the court to organize who is allowed to these new protections, and who is not. Everything, from proof of illness, to the form and reasons for a recommendation, is a potential weak link in a person's case.
Proposition 215 does not allow a person freedom to marijuana patients to use it anywhere, any time.
Proposition 215 contains a consition allowing that "conduct that endangers others" remains illegal. Such conduct is likely to include driving under the influence of marijuana, operating heavy machinery, or similar activities in which there is a realistic risk that a person's marijuana use could impair judgment and could lead to harming other people.
Proposition 215 was also made to protect ill patients from criminal penalties for using marijuana medically. Only people with their doctor's recommendation to use marijuana in medical treatment can take advantage of Prop. 215 as legal protection against marijuana charges. A doctor is the only person that can determine whether marijuana is the right treatment for a specific illness.
Most of the people who use marijuana as a medicine suffer from cancer, AIDS, or glaucoma; while some people state that it helps treat the symptoms epilepsy and other diseases. But having one of these diseases does not right away qualify anyone for medical marijuana under Proposition 215. Only a doctor's recommendation can do that.
There is now a pill form of a chemical in marijuana, THC, available with prescription under the name Marinol. Marinol's use is restricted to only cancer and AIDS treatment patients.
For some people, Marinol works fine, at least for a while. But for many patients, it is too expensive-costing up to $30,000 a year - or too strong or powerful; some patients say that this very concentrated drug "knocks them out," compared to marijuana in its plant form.
In the future, most patients have to buy or sell on the black market for marijuana. The acts of selling or buying marijuana are still illegal, but a patient who gets marijuana upon a doctor's recommendation is protected from criminal penalties for possession. There is no legal laws able to buy marijuana, but, in some cities, some clubs operate under some supervision by local authorities. These clubs usually require patients to provide real, written statement of their physician's recommendation to use marijuana. If the operators see that it is valid and that person has a true medical disorder, they will register the patient and allow that person to buy marijuana at that club.
