It depends on the amount you smoke in one sitting, and the amount of THC in the weed you smoke. It also depends on how skinny you are.

The detection window for marijuana in your system can vary based on several factors - body composition, metabolism, etc. Generally, for occasional users who smoke twice a month, marijuana can be detected in urine for up to 10 days after use, and in blood for up to 2-3 days. However, it can stay detectable in hair follicles for up to 90 days.
Your system should be clean if no other use during the last month.
In roughly one month.

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.
