Don't even try getting high on anything (Like drugs, alcohol, etc) cause it will never remain as a "One time experience". Once you like the feeling of getting high, I am sure you will get addicted.
I know I am sounding like your mom (Using a figure of speech here), but take my advice and don't get involved in such stuff.
If you really wanna know how the feeling of "Getting High" feels like, go mastrubate. I know this is unsafe for a moderator to post. But this is the safest alternative. I have read in books that consuming cocaine gives a prolong feeling of a sexual orgasm.
