Get the diphenhydramine mug.
Commonly used in OTC allergy drugs, like benadryl, a substance that has the ability to alter the mind to a dissociative and euphoric state. NOT a recommended recreational substance as it produces awful side effects like headaches, nausea, hot flashes, and much more. Although it does have some positive and creative effects which can include a heightened sense of time, closed eye visuals, hearing sounds or seeing colors, objects appearing to move or shift, and altered perception of vision. All in all, I do not recommended this drug for recreational purposes as you will have to pop nearly a whole entire box of allergy tablets (24 ct) to get high. So, just stick to that sticky green and you will find enjoyment in anything you do.
Austin: "Hey Alex," "wanna take some of that diphenhydramine and watch the seagulls talk to the ever inspiring priest??"

Alex: "Nah man," "I think I'll just skip all those BS side effects and puff on this premium Sour Diesel, a stoner favorite!"

Austin: "Let me pack my bong and I will trek with you on this journey to cloud 9."
