That makes sense to me. Selling anything illegal is a good way to get into trouble with the law.
The DEA isn't looking for people extracting DMT at home, but they will go after anyone who is reported to them. That's their job.
Lots of undercover guys go around looking for people selling at the mall, the parks, etc. If you sell illegal drugs to the general public, it’s only a matter of time before you get busted.
You should not sell illegal drugs, period, unless you plan on going to jail in the future.
The DEA basically responds to reports from the public. They are rarely ever proactive. They have enough reports to keep them very busy. If a mall shop seller reports to the police that there are people dealing illegal drugs in front of their storefront, the DEA will respond. If no one reports it, nothing happens. The DEA has a long never ending list of reports to respond to. They don’t have much time to find people on their own. They are too busy.
If you’re making DMT at home, and one of your “friends” reports you, you will get busted, even if you’re not selling it. Possession alone is a crime. And even if you extracted it for personal use, that’s still considered manufacture and punishable by the same laws.
If the DEA was actively trying to get people for DMT, they’d be busting all the on-line Mimosa sellers, and they are not at this time doing that. Sell of mimosa can, under the law in the US, be interpreted as selling DMT if the DEA chooses to. But they don’t. They don’t care about DMT right now because they get almost no complaints filed for its sell and manufacture. But if it ever gets popular on the street, that will change.
