I'm not senior here, but Boobs will confirm, I know my shit about this subject.

LAST MONTH I WENT ON A WEEKEND TRIP WITH SOME FRIENDS AND SMOKED 5-6 TIMES OVER THE COURSE OF THE WEEKEND. THE TIMES I DID SMOKE IT WAS OUT OF A SMALL BOWL AND USUALLY GOT 1 OR TWO GOOD HITS OUT OF EACH SESSION. THE WEED WAS REALLY GOOD BY THE WAY :P:rastasmoke: RECENTLY I GOT A JOB OFFER OUT OF STATE AND WILL BE FLYING OUT TO INTERVIEW. AFTER THE INTERVIEW I AM SCHEDULED TO GO FOR A HAIR Rating: 5
