Summary
Cocaine (also known as benzoylmethylecgonine, and informally as coke, cola, snow, blow, white, among others) is a classical stimulant substance of the tropane class. It is a naturally-occurring alkaloid extracted from the leaves of two coca plant species; namely Erythroxylum coca and E. novogranatense that are native to South America. The mechanism of action involves increasing levels of serotonin, dopamine, and norepinephrine in the brain.
Perspectives
“The slippery slope to addiction does appear to be less obvious than for most other drugs in this class. Be careful with respect to this: very careful.”

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Marked acute tachyphylaxis within a session; compulsion to redose creates binge patterns. Subjective tolerance tends to decline substantially over 3–7 days and approaches baseline by ~1–2 weeks in many users. Numbers are approximate and reflect anecdotal/clinical synthesis rather than formal PK/PD studies.

I decided to do a few lil bumps this morning to get me through the day and just to stop yawning so much. I’ve had this bag for weeks. Literally wasn’t even thinking about it.
Did like a half gram maybe a little more. Havent had any in like 12 hours. Been having bad chest pains since 6am after taking trazodone. Ive also taken cbd. I took my blood pressure and its normal, my heart rate is 89 Im so dizzy and my vision is so blurry.

Coke and Love This is the story of my fucked up nights of how coke took over my body and I fucking loved it then I lost the one thing I loved most. First of all Me and D are both best friends, doing hood rat shit like usual, together constantly.
The first time I did coke I was 19, and loved it, but did not do it again for a few more years. This story is about my experiences in my early twenties. I asked an aquaintance of mine for the name of a connection source.
I finally encountered cocaine. I wasn't really expecting to either, the beauty of Christmas Break. A friend of mine told me that he had located a friend-of-a-friend who was selling some acid and x, and that we should go by her house and pick some up.
What you are about to read is short true story about how Cocaine has effected my life, family, girlfriend etc. There will be no Bullshit so you may find some of the story a bit shocking or offensive. Names have been changed for obvious reasons Still Interested? Then read on.
I feel that describing just one experience with cocaine would do the substance a great injustice. Though it may seem straightforward enough - a euphoria-inducing stimulant - there is more more to it than meets the eye, at least in my opinion.
This report documents my first experience with cocaine. Background: I am a twenty year old male and I consider myself to be in good physical and metal health. I've grown up in a secular, yet still relatively stereotypical suburban household.
Hi In February of last year (2003), I did coke for the first time. It was really really good, almost identical in effect to Adderall, which I did a lot of previously. I got deep into coke for about a month after that experience, once doing a whole 8ball in one night bymyself.
Okay. Cocaine is something I have always been against, I've seen friends do it and overdo it. Two of my ex-girlfriends were heavy users of it and told me about their experiences. One of them was sort of reluctant to talk about it and always left me wondering what's so bad about it.

Coked up as fuck Introduction: This trip report tells the story of my best friend and me having a fun night on Cocaine together. I will explain the effects of this substance as detailed as possible.
Coke usage etc Ok, I couldn't figure out how to post in the right spot. Someone could also help with that. Lol. I did lots of coke and E and K amd probably other stuff when I was a teen and early 20's. I haven't done that stuff for a long time now (maybe 8 years or so) but I recently started snorting coke again.
(Cocaine / ~150mg) - First Experience - "Gemstar Razor, The Fruit of My Labor" Date: August 29, 2014 Time: 11:00pm - 3:00am Drug: Cocaine Hydrochloride Dose: ~150mg Cocaine is a very bizarre substance on just about every front.
Coke - 1st Time - B comes through again.... This is something that happened quite awhile ago,but the story coincides well with what's going on with me right now,so I feel in the mood to bust out this old gem...
Okay, folks, from my personal vault, here is an experience with a rather unusual compound which I had a one-off opportunity to sample a while back: β-CFT, a/k/a WIN 35,428, a semi-synthetic tropane dopamine reuptake inhibitor structurally similar to cocaine.
So, first time I did coke was about 3 weeks ago, and it was fun. I didn't do very much so the crash wasn't noticable, and the buzz was super nice. Went to a party and chilled with some "straight edge" kids who didn't know my friends and I were ripped and it was definitely a fun evening.
I had to join this group after what I just experienced. I am a new member and this is my first post. Combined with the absolute insanity I have just experienced, Ill ask if can forgive me if I break any rules this one time.. It won't be intentionally.
I've been very excited to try cocaine but at the same time very scared. Mainly because of all the stories about bad comedowns and the addiction factor. And I KNOW I have an addictive personality because both the drugs I've tried (weed and E), I totally have fallen in LOVE with! I don't do either very often but I'm alwa...
