I am constantly amazed by how many people view alcohol and marihuana as harmless. Even more frightening is the willingness of people of all ages to put unknown substances into their bodies that are produced by criminals who give the promise of getting high.
All psychoactive chemicals change mood by directly changing how the brain works. Small doses of brain-altering chemicals can cause serious problems with the ability to think clearly, manage feelings and emotions, remember things, use good judgment and control destructive impulses.

I suggest it is good idea to be very careful about the things we put into our bodies that can damage the brain. In make this suggestion with the same level of seriousness that I suggest you always wear a parachute when you jump out of an airplane.
“I have never used any mind altering drug that was not pharmaceutical grade. People who put drugs of unknown composition and purity in their bodies are either ignorant (they don’t know the real risks to the brain and mind), stupid (they know the risk and choose to ignore it), or addicted (they know the risk, want to stop, but find that they can’t). ~ Timothy Leary, in a private conversation with Terence T.
