Smoked 3 joints with one other person July 22nd and one joint July 15th
Have hair test coming up in about a week it is now August 15th should I pass a hair test
last time before that was smoked in april and may a few joints

A hair drug test is meant to show consistent use over time. A 1.5 inch sample, cut at the scalp, will go back 90 days. From what you described about your usage I would say you have a 80% (or so) chance of passing.

Thanks for the info
Test may be later then I thought so I guess every day that goes buy will increase my odds

They look for habitual use, so if you smoked a joint every day than you would be positive. I am not sure of the sensitivity of the test you're going to take but even if you had four or five joints than you're probably still good. The thing is they look at about 90 days worth of hair. The joints were in the last 40. More time is going to meant something if they test in October.

Thanks for the info
