I personally recommend if you want the best bang for your buck to insert your straw relatively deep at first but don't poke or hurt yourself. Then when you snort it, you don't want to yank that in with a huge inhale. Instead, just kind of softly inhale like you are smelling flower almost as you slowly pull the straw towards the front of the nose.

Your goal is to have a very fine dusty substance that you coat your nose with. You only really want it in your nose for like 15-30 mins or so max if you can help it. The majority will be absorbed by then and the rest is kind of insignificant.

(I suppose you could also mix it with 5ml of water and use a rounded tip syringe to insert it up your ass for the absolute best bang, but honestly i think that creates an entirely different high/experience)

It helps to practice good hygiene when you are using a substance that is often cut will some very caustic chemicals. Pure coke itself ain't so bad. The shit Americans get in the US... Put it this way, i never touched the shit in the US.

We get a lot safer product in Costa Rica. Yes it's a dangerous addictive substance but that's true about a lot of things. Coke addiction usually is caused by something underlying. If your life is perfect and you want for nothing and you do coke, you probably won't end up sniffing entire bags in one sitting. Some people might I'm sure lol some interesting people that choose coke I've seen.

(If you get unable to control your desire for anything you should probably seek help but especially true when it comes to substances that take a sound mind and head to prevent long term damage/death from)
