That depends on how much you've smoked and for how long. If you smoked a couple of times a week you would expect it to be out of your system within a month.
It could be out of your system in a week, or depending on the THC content of the weed, and your own body fat, as long as a month. And no, there is nothing you can do to clean out your system. Those detox products are BS.
Doesn't matter how long since you last smoked. Weed stays in your system from 2 weeks to a month.
