The definition of government is to protect the people. For them to do that, the people must relinquish some freedoms. The question is how much freedom are you willing to give and how much do you want back out of it.
Alcohol is more harmful than any other drug. Try to name one person on earth who has ever died from shrooms, peyote, LSD, etc. How many deaths occur each year from hard opiates like meth/heroin? Inconceivably less than the amount of deaths each year from alcohol.
I believe in freedom. Not anarchy. Just a sensible balance of freedom and protection. Drugs are a personal matter and are not to be interfered with by the government. Drugs have been used for thousands of years for spiritual purposes. No one on earth has any right to tell someone what they can or cannot introduce into their own body. Individuals should not be protected from themselves. That is an outright destruction of their free will.
