I meditate sometimes...but only if I haven't been toking all day.
If we've been in a heavy session (like, every day in the summer lmao) I just pass out around 8:00. Then I sleep like a baby until 6 AM, and repeat.
Any other time of year though, I usually meditate a little before bed. I don't spend the whole day smoking because of school and responsibility and shit...so, you know.
