I don't think it's too unusual. My roommate in college has thrown up about a dozen times. He described it pretty much the same way you did. When he takes a really big hit, he'll immediately cough and throw up, but after that he's completely fine. I'm not sure why it happens, but I guess some people are just like that.
MrDrinkingLysol Reviewed by MrDrinkingLysol on . Anyone else ever throw up when they smoke? I throw up somewhat often when I smoke. Not from the weed, from the coughing. Whenever I take a big hit and I'm thrown into a coughing fit, my brain sends this message to my stomach that says "regurgitate", then I puke a little then I'm fine. My friends are all pretty used to it, and don't get freaked out anymore. This happen to anyone else? Rating: 5
