Sorry to be do blunt but casually ignoring things like modafinil which seems to be the go to drug for staving off sleep if you want to be able to pass drug tests is a bit of a mistake.
Subjectivly most users of modafinil find it "weaker" than coffee because there is no rush associated with it as there is with coffee, you just can't sleep when you take it.
So if the point you're making is actually just virtue signalling with the "well some drugs are worse than others because I guess they are classified as controlled?" bullshit then please provide an actual reason why the comment was disagreeable.
