^True, and after 4 hours the actual mescaline effect is about to peak. But seriously can take up to 6 hours.
The most mescaline is right under the skin of the cactus. So don't cut the skin off but eat it with the skin!
Start on an empty stomach and eat as much as you can, just keep eating 1,5 to 2 hours if neccesary. Drink water and swallow the skin/parts if it's stuck between your teeth. Chew intens and suck on the parts! You should eat about 30 cm San Pedro for a reasonable effect, eat more than 50 cm and you'll have an unforgetable mesca effect.
Make sure you're starting with a lot of sleep under your belt. You should be cheerful 'cause getting tired on mescaline is no fun! Causes feelings of regretness and every irritation on the body and mind is contra to the effect of mesca. Also, don't try to throw up, cause the stomach pain will pass faster than you think, and deffo wastes mesca too!
You'll absolutly love this psychedelic, it's lovely, and make sure you can lay down. You might think you'll fall asleep, well you do, but the scenes in your mind are heavenly!
When walking in the nature, you eventually can cry a bit, which... truly mystical. Animals, plants, the sun and the night, the moon, you're all sitting in a circle with each other.
