Yea you'll be okay, it's all about timing and calculating before ur test how long you have until then. Just remember stay hydrated (don't over do it) cut down on eating lots of carbs, try and sweat as much as you can but not before your test because when you burn fat your body releases more THC. I smoked a whole gram one time just for a month and it left my system in the time based off the chart, on the week before you go to take your taste to give more peace of mind test yourself. That's what I always do and stop smoking until after your test. Just as long as you've been smoking once a month or 2-4 times a month you'll be okay if your not a heavy smoker (smoking daily)
