Will I pass my drug test?

...unlikely.           

you'll find out after your drug test

It’s iffy. Weed can stay in your urine for up to a month or longer, but it can also be much shorter. The fact that you work out helps, and you’re a regular smoker but not a heavy smoker. I suggest you keep working out, but avoid the gym for a few days before the test. You can take a home drug test a day before to see if you’re clean. Starting on the morning of the test, drink a TON of water. You should be peeing clear, and very often. Keep drinking even if you aren’t thirsty. You’re trying to dilute your urine. When you take the test, pee a little in the toilet before and after filling the cup. The beginning and end of your urine stream have the most toxins. Don’t bother with any of those detox drinks. They don’t work. The only way you can pass a drug test after doing drugs is to either dilute the urine, or use someone else’s pee. There’s a good change you’ll pass, but it’s definitely not a guarantee. 

You should be fine, it takes about 2 weeks for THC to be out of your urine.

There are no detox kits that actually work.  The only detox method is time.  Doesn't matter your age or weight or how much you exercise or how much you drink or what your favorite color is.

If your friends smoke Second Hand smoke will contaminate you, your clothing, furniture is all contaminated too. the Dust is everywhere you live even in your/friends car upholstery.

Most smokers are groupies. that means your friends are contaminating you with second hand smoke. Plus the smoke residue is in your clothing and furniture fabrics (and car). So you are getting micro-dosed everyday with it.
