Dear FrENTS, in 9 days I will be smoking for the first time in over a year. I need some help/advice.

Thanks for taking a moment to read this, it's much appreciated.

So, in 9 days I will be getting home and will be able to toke some sweet mojo, and have about a month to do so before another 11 months of sobriety. I need some help/tips figuring out how to go about making the most of my 30 day escapade. My friend has offered to hook me up with some 'Blue Hawaiian' for $45/8th (not sure if reasonable price... or getting ripped off?) and my questions are as follows:

What would be a reasonable amount to last me 30 days of smoking probably 2-3 times a week? (and hopefully sharing some with the lady-friend) Are there any tools I should get? (Grinder, etc?) Should I get a glass pipe, papers, something else? Also, what types/strains are 'worth' the extra $10-15 an 8th? Is there any way to tell good weed from meh stuff? And how do you guys keep yourselves concealed, ie, good ways to hide a stash, keep from looking high in public, etc.

I did smoke a bit last summer but mostly just because my friends offered to smoke me up, and I never really learned how to do it properly on my own.

I'd really appreciate some help and some insight into this stuff, and tips&tricks are also more than welcome. Thanks everyone:)
