Your body needs to break a THC 'threshold' to get high. This means that you need to smoke a crapload your first time to get high. Here are the tricks:

Always buy the best weed you can get for your first time. Money should be no object. Don't do it just to do it. Make sure you do it right.

If you don't know how to distinguish good weed from bad weed, then find someone you trust who can do it for you. You want White Widdow, Train Wreck, Diesel, BC Chronic, Blueberry, or another very well bred and grown strain. You don't want some crappy ditch weed from some two bit dealer.

The good thing about smoking joints or dry pipes is that they give you the hardest hits. This will get you high the fastest, provided that you can hold it. The good thing about bongs is that they filter the smoke so that it is less harsh, so that you can take more and hold it longer; but bongs are usually tricky for beginners and they waste weed when they are furst learning how to use a bong.

The very best method for your virst time would be out of a vaporizer. They are simple to use, and it's pretty much impossible to take too big of a hit of vape.

Hope this helps.
