You took too much

You have more THC in your bloodstream than you are comfortable with, and your body is processing it at its own pace. The usual presentation is anxiety or paranoia, a fast heartbeat, dizziness, nausea, and a distorted sense of how much time is passing. None of that is dangerous in a healthy adult, and all of it is genuinely horrible while it lasts.

There is no known lethal dose of THC for an adult. That is worth holding onto, and it is not the same as saying there is no risk — the real dangers around a large edible dose are falling, driving, choking while asleep on your back, and an existing heart condition. Lying on your side somewhere safe removes most of them.

The peak usually sits two to four hours after eating, the main effect runs four to eight, and there is a tail after that. If you are reading this an hour in, the honest answer is that the worst is probably still ahead of you — and that it will still be over by morning.

It will also come in waves rather than easing steadily, so a stretch that feels like it is lifting and then returns is normal and does not mean it is getting worse. The full timeline is on how long edibles last.

• Eating more food. It cannot absorb what is already in your bloodstream. Eating something plain is fine if you feel sick; it is not a remedy.
• Coffee or energy drinks. You end up alert and anxious instead of sleepy and anxious, which is worse.
• A cold shower. Bracing, briefly distracting, and does nothing to the drug.
• Making yourself sick. If you are feeling it, it has already been absorbed. Vomiting adds choking and dehydration to the evening without helping.
• Black pepper, lemon, CBD. All widely repeated, none well established. Harmless to try, so try them if it helps you feel less passive — but do not count on them, and do not take more cannabis of any kind.

You may feel slow and foggy into the next day, particularly after a large dose. That fades.

When you are ready to work out what went wrong, it is usually one of three things: the batch was stronger than you thought, it was not mixed evenly so one piece carried far more than its share, or you redosed inside the two-hour window and both arrived together. The infusion calculator will tell you what your butter or oil actually was, and the batch log will keep the answer on the jar so the next one is not a surprise.
