It is a really strong type of tobacco. The buzz it gives you is similar to the first time I tried a cig, except the first time I tried a cig I didn't fall over--Had I been standing while trying Dokha I would've fallen over. The buzz is so intense it's recommended that you're sitting or even lying down when you try it! And yet the Arabians smoke it like we would cigs. It's nuts. Though after awhile you do get a tolerance to it, but still.
To be honest, I once smoked Dokha after doing acid (baaaad move) and it made me stop breathing. I don't remember if I started coughing or choking, I just remember I couldn't breathe. So, if you try it, I recommend trying it while sober.
