That statement alone is tells you he is soooooo bullshitting. Let's see, he is a major rockstar in the 80s and he smoked pot once and got sick. SUUUURRREEE! Goes along with the line of he never cheated on his wife either - aha.

I do respect his attempt to give a clean impression if not for his own image then to avoid any potential fans wanting to follow in his footsteps and of course for his kids sake.
