that stuff is good. it really depends what brand you get though. in my opinion, some brands are too intense-
mary joy pink is a uk based herbal incense and it is fucking potent. you might freak out your first time. might. also it is orally active but i don't recommend it because it caused intense paranoia and hallucinations.
right now i've got black magic incense. i like this one because it's smooth. it doesn't cause the anxiety that mary joy does but gets me BAKED. its basically the crack of weed. you'll get super baked for 15-30 minutes and then feel mostly sober although you might still be chink eyed and you'll crave more.
low doses feel like marijuana but as you inhale deeply it gets a really cool dissociative feel. you start to feel like you're slipping out of earh into a different plane like heaven or some other planet like the matrix. also everything looks beautiful the trees, the plants, its awesome.
now i don't advocate using this, nor do i advocate stupid minors smoking j's with their friends and complain to 911 and then get on the news and then the government gets angry were all getting high and then they ban the chemical, and then these manufacturers have to start all over again just to move the cannabinoid by adjusting a carbon atom or something.
also i don't know for sure but i think the herbal incense i have now contains ur-144. i don't know for sure though and you can bet your ass the company won't tell because they want to keep it a secret.
