Just tried cocaine for the 2nd time

[sina]

ok, i got a question. but first let me tell you my experience

i was lying down, light was out, closed my eyes, etc. i think that the dose actually did affect me, but only at the end. At the end, i felt like i was spinning a bit, and like my legs did some unusual movement, and my muscles were contracting. Also at one point, my friggin eyelids were blinking fast, and i could not control it. but that stopped after like 20--30 seconds

But it didnt give me clearer thinking skills and enhanced concentration. is this normal?? did it work?

since this one worked (or atleast i had some effects) does it mean that i could try out others and get an effect there too or what?

oh and by the way, is Marijuana good? i want to try it

Thanks!
