How many 512 perks get you high?

Answer 1

Depending on your opiate tolerence two-four should be enough.

You can do the following :
Take oraly by swallowing, which gives a nice longer lasting mild high.
Or Parachute by crushing them into a fine powder and putting in a single layer napkin and twisting it up into a ball, sorta like a tear drop. Swallow and be prepared for euphoria in 1-2 hours :).
