I agree that it is the fact that Etizolam is a triazolobenzodiazepine or thiendiazepine that gives it other qualities than normal benzodiazepines.
Etizolam
4-(2-Chlorophenyl)-2-ethyl-9-methyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine
The upper phenyl ring is replaced by thiophene compared to for instance diazepam, alprazolam and oxazepam. This adds potency and the thieno and triazolo adds the special effects people experience from Etizolam compared to other benzo's.
Regarding brotizolam, there's an even stronger version;
Flubrotizolam
2-bromo-4-(2-fluorophenyl)-9-methyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepine
Flubrotizolam is probably one the most potent and hypnotic RC benzo's that can be made right now. In years people have been speaking about the possibility of making it, and now vendors in China and Indonesia have it listed for sale. So we might see it on European and American RC sites if it is for real. In some way I hope we do, because I wanna try it :D But I think it will be so potent and hypnotic that we will see an enormous amount of people experiencing black outs as they cannot handle the potency which will make policy makers focus on the RC market again. It might be so potent that we have never seen anything like it. But currently, it is available on Asian sites, whether it is actually Flubrotizolam that they have made succesfully is another question though.
It is closely related to
Flubromazolam
8-bromo-6-(2-fluorophenyl)-methyl-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine
You can see how Flubrotizolam both have the thieno and triazolo ring like Etizolam does. So I think it is the combination of the two that makes the greatest change from normal benzo's.
Normally you say that benzo's with a nitro ring is the most recreational, like:
Clonazepam
1,3-dihydro-7-Nitro-5-(2-chlorophenyl)-2H-1,4.benzodiazepin-2-one
Clonazolam
6-(2-chlorophenyl)-1-methyl-8-nitro-4H-s-triazolo- (4,3-a)-(1,4)-benzodiazepine.
But for me the combination thieno and triazolo rings seems to be the most euphoric benzodizepines. But it is so subjective which benzo's people like the most and how they influence people are also very different. Etizolam is by far my favorite benzo and on a shared second place we have clonazepam and clonazolam, but they are in no way in the same league as Etizolam. I really mean it when I say that sometimes I experience so much euphoria from Etizolam that I like it better than opiats, and I cannot live with opiats, so it really says a lot. I wish I could find out why it is only sometimes that I experience this euphoria.
Back to the topic.
It is one hour past midnight here, I have been dipping into the cocaine I have purified, so I have had an absolutely wonderful evening. Now I am starting to mix ketamine into the lines so I will experience a K-hole and fall a sleep after that. Last time I experienced a K-hole it was like I was in a world like HBO's series Westworld, it was so strange
. Which is fine I suppose.
