my best friend from high school told me he sold his soul and after 3 years of not seeing him and 3 years of him doing heroin. he turned. i saw him not knowing what he had done but it was not the same person. had to make him leave my apt within 45 mins of being around him. not the same guy. 

be careful. you can lose yourself and some drugs will push you there. some drugs are evil.

Literally same thing happened to me. Friend came over after not seeing him for over a year, and was freaking tf out on heroin. Kicked him out, came back a minute later with a Ouija board doin devil shit in my patio. Then he tried to attack my neighbor in the parking lot. Cops came and arrested him. A few years later another friend told me he found the Ouija heroin friend on social media and hes a tranny now. Feels sad man.
