How long do edible effects last?

Edible effects typically last 4-8 hours, with peak effects around 2-4 hours after consumption. Some users report residual effects the next morning with higher doses.

What's a good starting dose for beginners?

Most experts recommend 2.5-5mg THC for beginners. This allows you to gauge your sensitivity without overwhelming effects. You can always take more next time, but you can't take less once consumed.

Why do edibles feel stronger than smoking?

When you eat cannabis, THC is processed by the liver and converted to 11-hydroxy-THC, which crosses the blood-brain barrier more effectively and produces stronger, longer-lasting effects than inhaled THC.

What should I do if I take too much?

Stay calm - no one has ever died from a cannabis overdose. Find a comfortable place, stay hydrated, and try to sleep it off. CBD may help counteract some THC effects. The intense feelings will pass, usually within a few hours.

Do edibles affect everyone the same way?

No, individual responses vary significantly based on metabolism, body weight, tolerance, and even genetics. Some people are naturally more sensitive to THC. Always start with a low dose to understand your personal response.
