You are wrong bro, bringing in any substance over a federal border that is a controlled substance without authority to import can attract a charge of "Importing a controlled substance".The law is to keep physicians from prescribing steroids for off label uses like body building and an ammendment was later added to include hgh, but whatever. You think you're right so go ahead and try to scare people on here with your irrational fears. I'm done discussing this.
If they do a controlled delivery or raid and find you in possession of a controlled substance, that's going to result in a "Possession" charge.
A raid will result in all your electronic devices being cloned as well and they will have full histories of what you have done online, passwords, websites and so on (Everyone interested in basic OpSec should learn how to setup and use a USB hard drive with Tails OS at a minimum... Sure, its not convenient but it can certainly save your ass if shit ever hits the fan!)
Anything over "personal use" is automatically deemed to be dealing, so they will throw in a charge of "Distribution" as well. Personal use amounts are what is used medically (aka fuck all dosages). Decent lawyer should be able to push back on this 1 unless they have evidence of you dealing.
Raws will also attract a charge of "manufacturing" (decent lawyer will push back on this and make them prove it though). If you get caught with cookware and all the associated, they can back up the charge.
Is it likely someone gets popped for it.... Low.
But that doesn't change the law and the way it can be enforced! Every few years they seem to circle back to PED's and do a crackdown and you will hear a heap get done.
If the drug falls under a controlled substance heading, its illegal to posses without the authority to posses it, plain and simple.
Its not about trying to scare anyone, its about understanding the risks and taking steps to minimise them BEFORE your front door is getting kicked in. Understanding the risks and taking steps to minimise them can mean the difference between getting off charges or ending up doing actual time.
