MXE does. So does 2-Fluorodeschloroketamine, deschloroketamine, and several others. The issue is once you step off the PCM chain you have hider chance of a side effect of mania.
MXE does have the same bladder issues, but is taken as a smaller dose so it takes longer to happen.
I'm also seeing quite a few more people operating on multiple sites at once now, even SFW blogs. So they'll post Tumblr, Pillowfort, and Wordpress at the same time so their former users can still see them.
Fentanyl doses in micrograms I believe. A lot of addicts are addicted to the feeling of the injection and the ritual of it as well.
Heroin I believe doses in the tens of mgs, which is hard to measure precisely but can be weighed on a twenty dollar scale. You could distribute fent in the same way Lsd is on blotter paper. The big difference is you accidently get a hot spot of Lsd it's not fatal.
Many addicts aren't buying massive quantities at once either nor are they getting it from the internet.
I agree with you on that bombs thing. Currently USPS mail is very underscreened. All (or almost all) drugs in the US and coming in use USPS mail due the fact they need a warrant to open your package.
They currently have greatly stepped up their screening game though, mostly due to fentanyl. But that doesn't mean you have to ship straight to the US in bulk. A common route for fake pressed xanax was alprazolam powder to canada where it was pressed and either reshipped or smuggled into the US.
Your argument would work better if the EU wasn't also source for this sort of thing. Though the availability on that end has gone down due to a Russian lab being busted earlier this year that turned out to be behind two of the bigger source sites.
At a certain point people just stop buying drugs unless they're heavily addicted. The thing about research chems is that the ones that tended to stick around dose in the sub 50mg range. The cost per dose is still low since they're produced in multikg batches, resold in fraction to multi gram increments.
No you're right but what it lead to it was sites like Reddit closing down things like /r/darknetmarkets, and /r/rcsources which are both review and sourcing subreddits. It made other forums scared to touch the idea of sourcing because the act can be used against any illegal activity.
So something they briefly touch on is new research chemicals. What they don't mention is what happened earlier this year.
FOSTA has slaughtered many avenues of sourcing research chemicals. It is significantly more difficult to get them from a reliable source then it was this time last year. While this doesn't stop anyone sufficiently determined, it's harder to get a source of say fentanyl or U-47770 to cut with.
The US has been cracking down on producers of these in China, and many chinese or US based resellers have either ceased to exist or changed their operation (US seems to be heavily targeting opioids, China seems to be going after ketamine and analogs) . In addition the Darknet Markets have taken a big hit from Operation Bayonet. It's not to say that DNMs or their vendors or customers are gone, just they're finding it harder to regroup. Though there have been a number of high profile busts from the data of Operation Bayonet
This applies to more then just opioids though. Other drugs with overdose potential, like stimulants are just harder to get a hold of. Most US domestic sellers seem to focus on benzodiazepine analogs.
We'll see how long this lasts though, I doubt that whole scene is truly gone but it might just be in hibernation for a bit.
This probably isn't healthy but it's the easy coping mechanism for the problem of not socializing enough.
