Hello and welcome.
In short, no there is no easy fail proof way. As far as safety is concerned as long as your are using the cocaine and baking soda your concern is really more of not doing it correctly to the point that you lost all or almost all of it. The best way for me to learn was have someone who knew to show me. There are videos on youtube...
My best advice is to not cook it. Its a waste in my opinion and i regret every dollar or ounce of product Ive cooked in the past. You should really stick with powder. Im not encouraging the use in any way/form but there are 3 main ways to use cocaine and crack to me is the worst most overrated wasteful way. I personally prefer the other 2 ways a lot better, Do yourself a favor and just dont. And when you do because your going to do what you want anyways, be prepared to loose some at first its not rocket science but it takes a bit of experimenting to get efficient at it. Please stay safe and clean.
