Mr. Morris, I have tried to guide my child toward a life without artificial stimulants.

"A debt in your sleep bank account is not reduced by artificial stimulants."

Not all students rely on artificial stimulants.

"And do these, er, jokes require the preparatory use of any form of artificial stimulant?"

We Vulcans have no need of such artificial stimulants.

"No civilized person uses such artificial stimulants anymore."

Then they use artificial stimulants, like caffeine, to mask their sleepiness during the day.

All sorts of artificial stimulants and nourishments pumping in, as well.

So you do get what I call artificial stimulants.

I know that the people who started Earth Works make a big thing about renouncing all artificial stimulants.
