About the drugs

I think that some topics of drugs are dangerous, especially drugs that are chemical compounds, as they are highly addictive and the body just never assimilate. Drugs like cocodrile, cocaine or pasta base they really are the wastes of other chemicals, besides when consumed long time do much damage in the body and mind. Addicts lose all their powers of thinking or acting "freely".
Of course that not all the drugs produce this effects, cannabis for example produces a state of relaxation that can be very beneficial to sick people, even for people who are not. The problem with marijuana is advertising and myths around it, because this drug is less addictive than cocaine, for example. Also is false that cannabis produces neuronal damage, the problem is when it is processed and mixed with really harmful drugs that can contain.
Regardless of whether for medicinal or recreational use natural drugs, like marijuana, salvia, opium, among others, should not be punished or restricted, especially if it is self-cultivation. Because the plant is not really harmful, but misuse or processing them.
 I think that banning the use of (at least natural) drugs is stupid enough to restrict plant growth. Also, if the problem is drug addiction must consider various foods we consume daily that produce addiction, such as coffee or chocolate; and if the problem was the harm caused to our body no food or things of everyday life that also hurt and are not necessarily natural.
I think the state should not interfere in the use you give to plants and that marijuana should be legalized.
