I've tried 3 types of khat in my life,
my first experience with Khat was 4 years ago, I was sold a capsule which the guy said was 'Khat', it had little dark brown and tan balls in there and told absolutely not to snort it. It was a large 800mg capsule~. I got a very strong amphetamine like buzz from it, dance nonstop for ~6hours before a nasty crash and not being able to sleep for about 36hours.
Second time I had khat, it was sold as Qat and was a white powder in a capsule which were 120mg each. Had an extremely strong odor and gave a nasty drip in the nose when snorted which would make me almost vomit quite a bit. Gave a really nice clean amphetamine like buzz without the jitters or sketchiness. Was one of my favorite's to take for a while before it went out of fashion. The high only lasted about ~4hours. Test kits did not respond to the contents of the capsules but source said it was Methcathinone. (I have never had 4-mmc so can not say if it was actually 4-mmc or not. My assumption is that it wasnt mephedrone because it was sold as Qat and was in 2006-2007)
Third play on Khat was from fresh leaves from the narrow and vanilla white strain mixed together. Was only about 8leaves from a young 2 year old plant. Got a small buzz bit stronger then caffine (i have high tollerence to caffine, get next to no stimulation from it, so can't really compare it to khat). It helpt me study and such, but because the plant was so young I can't really comment on how good the buzz is until I come accross a more mature plant wiht decent mouth full of leaves. All I can say was that the leaves were not sweet at all from the narrow leaf, they are infact extremely bitter!
That first 'Khat' I tried, the small brown and tan balls in capsule, was probably the stronger and most fun buzz I have ever had. I have always wondered what it actually was, wether it was khat leaves dried or not? I know nobody here can really tell me and it's against the rules, but i've never come accross anything like it before or since! Anyone else? I miss it, it was amazing.
