How much avb should I use?

If a 5mg edible gets me super high how much avb should I use? Should I use a teaspoon? I just don't wanna get too high and 5mg already pushes it. I have a low tolerance lol. Also should I blend the avb in a food processor or get a coffee grinder? I plan on using the avb in hot chocolate that I have. Many thanks on any advice or tips! (I couldn't post in the avb subreddit unsure as to why)
