Whats the quickest, trustiest from of cleaning thc out of your system?

I have been smoking marijuana for several years, more so recently. In the past year I probably smoked on a near day to day basis. I understand smoking isn't legal, or "publicly accepted", but Id much rather catch a buzz from smoking an herb grown from the earth than drown my sorrows in a "publicly acceptable" suicide attempt. I rather enjoy having a liver thanks. So that being said, I would love to be spared the mkay speech about how weed is going to ruin my life. The only reason I wish to clean my system out is to pursue a new career and leave my workplace of 4 years behind, I get bored easily. So if anyone has any knowledge of the sort, please ist me in my quest to be thc free! Thank you very much.
