Yea you're right burrows,
'Frank Zappa tried cannabis ten times, but without any pleasure, and "never used LSD, never used cocaine, never used heroin or any of that other stuff." Zappa stated, "Drugs do not become a problem until the person who uses the drugs does something to you, or does something that would affect your life that you don't want to have happen to you, like an airline pilot who crashes because he was full of drugs."'
