Hey man. Welcome.
Youll get all kinds of advice in this open forum. Lots will be shit, lots will be for a laugh, lots will be well intentioned but bad ( ie coke can pipe ) and then youll find the well intentioned good advice.
The problem is you have to sort it out yourself and hope youve chosen the good advice.
So, that said Im not even going to offer up any advice without asking you a few questions first so I can cater an answer for you.
So, how old are you?
Do you know anyone else who smokes?
How much do you weigh approximately?
Do you smoke cigs?
What is the worst case scenerio if you get caught smoking pot?
Do you have any fears or apprehensions about pot?
What made you decide to try it out?
Do you live city or country?

Trust me , its all relevant. Im not going to offer up advice blindly friend.
In turn I will answer any question you pose to me? fair enough?

peace.
