A while back
SWIM met up with a friend to get high. His friend had gotten him some stuff that seemed to do the trick but they didn't smoke very much of it. His friend kept complaining that it wasn't strong enough even though SWIM thought it was pretty decent. SWIM hadn't smoked any for years at that point so it was possible that SWIM's tolerance was letting him enjoy crappier dope.
Later in the night SWIM's friend convinced him to get more from a different dealer, at which point they went on a quick journey and got some. It looked great, crystal clear shards and it all came back very nicely in the bowl. SWIM was letting his friend do all the loading because he can be rather controlling like that sometimes but it didn't bother SWIM since he was getting high regardless. After SWIM's friend loaded the pipe he passed it over for SWIM to take the first hit. SWIM took a huge hit because it was loaded rather generously... during the first hit something from the stem had hit the back of his throat which made him cough a bit.
Thinking it was just dope SWIM assumed it was just excess that got left in the stem from stem loading. However something strange happened, SWIM couldn't hear anything over a loud ringing in his ears and his head started to spin for a minute or so along with blurred vision while he friend was saying something out loud that he couldn't make out even after asking him to repeat 3 times. When the ringing stopped SWIM was extremely high at this point and his friend never took a hit out of the pipe, nor did a friend of SWIM's friend take a hit.
Anyway fast forward a bit, SWIM's lungs were burning a bit for the next week after that. SWIM is pretty sure something was mixed in there but he's not sure what it was exactly. Has any else experienced something like this? Is it possible that it was just some really strong shit? SWIM has heard of ears ringing from doing shots but never from smoking.
