First things first, take a deep breath and remember that no one has ever died from a marijuana overdose. But it is hella uncomfortable. I’ve been there; I understand. Here’s what you should do:
Take some CBD. CBD counteracts THC and will level out your high. This is by far the best option and good to just keep on hand if you partake regularly. If you don’t have access to that right now, there are a few things you can still do at home.
Sniff some black peppercorn. I’ve never tried this one personally, but lots of people swear by it. I know your ass is too high, so I have to say this. Do not literally stuff your face in the pepper shaker. You’re gonna be sneezing out black pepper for days. Gently waft the scent to your nose or smell whole peppercorns.
Stay hydrated. Avoid alcohol and don’t consume any more cannabis. Take small, frequent sips of water or a non-caffeinated beverage and try some light snacks – peanut butter, cheese, nuts, lunchmeat, fruit.
Relax and try to sleep it off. Remember, no one has ever died from an overdose and this feeling will pass. If you’re having trouble actually falling asleep, just get comfortable and focus on breathing in through your nose and out through your mouth.
Stay focused with an enjoyable activity. Listen to music and dance! Play a video game. Watch some tv or a movie. Color in an adult coloring book. Play a board game or card game. Getting your mind off this feeling will help you ride it out. Don’t panic. This too shall pass.
