Hard to say really, there's a lot of things I like to do when I'm high. Video games. Masturbate. Watch TV shows like It's always sunny or the Chappelle show. Go lay on my bed and close my eyes and go flying or down a waterside. Chill and listen to music. Browse the web and go on places like Grasscity, Cracked.com, etc. Look up stuff on Wikipedia. Watch funny movies.
Masturbate is number one on my list So fun and intense, but I've only had the chance of doing it once. I love watching the sun set over the water at the beach near my house. The colours are so beautiful and I feel like I can appreciate it in a way that I couldn't before while I was sober. The colours are much more vibrant when I'm high, so I feel like I can appreciate nature & art a lot more. Also, baking cookies (normal cookies) and then eating them with a friend or someone you love while your high is honestly such a fun thing.
