While your probably a little tolerant, I don't think it's just that. You don't suddenly wake up one day immune to THC. Even shwag will have some affect. Your dudes probably keifing it. Get yourself a pocket microscope and check before you buy. My dude looks at me like I'm crazy but I ain't buying no keifed bud!
actually no. I smoke 15 times a day. But with good organic hand trimmed buds had no issues get relief. Now since moving here backk to my birth town in Cali its bad! I never thought Id have to say that!
