A personal stoner is a stoner that spends the majority of his time smoking cannabis by his or her self. these kinds of Stoners are more in-tune to themselves, due to the countless hours spent smoking weed alone, they gain a great knowledge of there own personality and themselves as a person. They are mostly anti-social besides there personal friends and tend to act weird around other people.

Alex (Joe's friend): dude... your high as fuck. you have been talking to your cat this entire time.
