Trying To Figure Some Things Out

Hey GC!
 
 
My friends call me Smokey or Killigan. Up to you guys if you feel the need to go by a name.
 
I've been smoking for about 5-6 years now and usually in 2-3 weeks of not smoking, I'm pretty good when it comes to be clean for tests. But I was also pretty active at the time, and wasn't as unhealthy as I am now. I've recently quit doing the most unhealthy things, like drinking soda, sitting on my ass all the time, etc. and now it's time for me to get a job according to the ol' man. So I gotta get clean and figured I'd ask on here to see if anyone had one of those crazy tips/secrets to flush toxins out fast.
 
Here's my "body stats" I guess you could say:
 
Height: 5'6"
Weight: 192 lbs
Age: 18
Activity level: I work out every other day, walk around town with friends, ride my bike with friends
Amount Smoked: Well, we've spent over $300 in weed and smoked all but .5 in about a week. Plus another 3 grams before that..(School's been out, what can I say other than I like to party?) Side note, it was medical grade bud.
Other Stuff: I quit drinking soda about 2-3 weeks ago after realizing how bad it really is, completely dropped smoking cigarettes about a month or two ago except for one time last week and I was riding my bike while smoking it. I drink a shit ton of water and had maybe a 5th of alcohol this week.
 
My plan is to work out a little more, or ride my bike more. Just something to get me up and moving around so my heart is constantly working harder than normal. I was also going to start taking Niacin (the flush kind, not Flush Free) and just as a last resort, go and see if my local headshop has synthetic piss I could get.
 
Also, if it means anything. I'm trying to get a job at BestBuy as a Sales Associate so I can be out on the floor. I feel like I can pull it off, I've been modding Xbox consoles and have basically been around electronics all my life and I usually know what I'm talking about when it comes to Xbox's and Computers. Not so much Playstations, but I still know a bit about them.
 
Sorry to add to add to the plethora of spammage of the same ol' question found on Grass City
 
Thanks for taking your time,
Smokey
