I have a couple of general rules that I try to apply to my existence: don't do anything too addictive, don't do more than planned, and don't redose anything on consecutive days. I follow these rules, and my body is thankful. But to be fair, this was a special occasion.

Tolerance
Build-up
develops within days of regular use; analgesic tolerance faster than respiratory depression tolerance
Reset
7–14 days for partial reset; full reset may take weeks — tolerance loss greatly increases overdose risk
Tolerance Decay
Full tolerance

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.

I had grown my own opium poppies and was quite frankly very excited to try a substance that would hopefully be more enjoyable and memorable than cannabis. I cultivated the unrefined opium from the poppies (Although it is quite illegal where I am, as it is a schedule I narcotic, so if I was caught and convicted of Consp...
If you love opium but find it hard to get and alot of effort to grow, you'l love this. about 10 or so weeks ago I met a guy who said you could get high off poppy seeds. (what a load of shit, i thought) but wanted to try it any way so i asked him if he could grab some for me.
Friday, April 13th is a date I will not soon forget. I was alone at a local club to see one of my favorite local bands. The place has a very cozy or familiar feel to it because of its small size, couches, pool tables etc. I met a few people there and had some good conversation about music.
This is the story of my relationship with Opium. When I first encountered it I was about 23 and experimenting with various drugs. Some of my friends started bringing opium resin to smoke during our lazy afternoons out in the countryside, I never smoked with them but curiosity grew and grew until I decided to buy half a...
This may seem curiously similar to a previously written story, but it's unrelated although reading the other story and seeing that there were only 11 entries in the opium category did inspire me.
We had hiked six hours into the jungle, somewhere in North Thailand; a typical hill trek to a Karen hill-tribe village that the backpackers and tourists commonly do. After dinner, after the rest either went to bed or drank with one of the guides, I took the other guide aside and expressed my interest in opium.
First and foremost: I want every reader to know that I have a there's a difference between addiction and fascination . I am fascinated by drugs and the history and culture that encompass them. I could be addicted to beer if I didn't have to drink so much liquid.

DISCLAIMER The dosages used in this thread are very high compared to typical dosage ranges described in literature. This may either be due to a weak product or my god-given morphine tolerance.
About 3 years ago I tried my first opiate (hydrocodone) and didn't like it at all. I kept at it, though, and eventually found how to obtain amazing experiences and useful effects from them Dose : 2.33 tbsp (7 tsp) of dried poppy powder downed with orange juice along with; * 30mg DXM for potentiation and reduction of to...
Opium - First time - remix addition X_X Alright, it's been a while...but I still remember it very well. I'll edit it with some rough estimates on time and add my next-day experience/etc.
I have been using poppy seed tea daily now for almost 2 months, however drinking down 2cups+ of rancid tea everyday is beginning to REALLY annoy me. A few days ago i read about poppy seed opium, so i decided to give it a go.
[some one I know] tried the opium extraction and this is what he did: 1) Placed 500g of poppy seeds into a 1.5L container with a lid 2) Poured 500ml of methylated spirits into the container 3) Agitated the mixture for about 10min and let sit for another 20min 4) Opened the cap just enough to let the liquid out and pour...
As we all know, real opium is an extremely rare thing to come across. Most of the time, when you find it on the street, it's just tar heroin. So of course I felt very fortunate recently to obtain a chunk of very very high quality opium (and yes...I am 100% absolutely sure it's real).
Hi All, just a bit of background, I'm on day 23 after quitting oral opium (pods and tea) for good. Just felt DONE with it. But earlier today i was talking to an acquaintance about the US's OD epidemic, even I usually stay away from that topic as though it doesn't interest me, to hide my intimate familiarity with the su...
