Absolutely not

The trimethoxyphenyl moiety carrying a three carbon chain has of course been seen in mescaline, TMA and the like, but no active compound of the psychdedelic nature lacks the amine functionality, which I would say is essential for binding within the 5HT2a receptor binding pocket.

I'm concerned with chemistry, not the law. The two have very little in common, the lawyers try to have chemistry be what they want, not it simply is, regardless of the wishes of its users. I say no active psychedelic lacks the amine functionality, that isn't STRICTLY true, there are the likes of salvinorin and its derivatives, but when I speak of 5HT2a agonist psychdelics, they always possess a sidechain of varying length, between 2-4 carbons long usually, bearing a terminal amino group.

Edit-I couldn't give a shit what politicians think of me, and Tsathoggua? he would just rip their arms and legs off, to use as chewing gum. But The way the law stands in the US is disgusting, even more so than in the UK, it seems like there is some national panic being continuallly stirred up about the evils of 'drugs' those anonymous (usuallly) crystalline powders, or assorted collections of xenobiological tissue that isn't, here in the UK where I am, and certainly not in blackest N'kai where THAT guy is. Down there, there are no coppers, and certainly no DEA, only the formless spawn, who dissolve unwelcome trespassers, not many are welcome down there.

^^^^ No synthesis is in the cards Enkidu. I plan to use chemical as is. No modifications of any kind would be made to this chemical. No glassware, equipment, or other chemicals of any kind would be in possession at same location or anywhere else. Just this chemical and that is it.

As far as the analog act is concerned, 3,4,5-trimethoxystyrene is substantially similar to a schedule I controlled substance.

Legally, however, it does not fit the second prong of the test (ruled by the courts to be AND, not OR) requiring that it have a psychoactive effect substantially similar to or greater than its schedule I counterpart, mescaline.

Enkidu is right. The pitfall here is intent, which might lead to charges of attempt or conspiracy

All it needs is an amine group on that double bond on the carbon chain... how hard would that be...
