Less than a month. Smoking more often than that stays in your system for 30 days, so 6 hits is nothing.
Forever.
Four hits in one hour
Max 3 hours. Stop worrying. I've smoked it since I was 15 and its done nothing but good things.
About 1 month.
for about a hour
It depends on how often you consume marijuana, your weight, and other factors. The marijuana will be the last to leave your system and can take a week to 60 days.
About a month
Not using any for a long time will do it.

Just as long as 30 hits do.... it stays in the system up to 30 days and will end up in any body hair grown during that time and will remain in the hair until it is removed from your body.
Marijuana can typically be detected in urine for up to 30 days after occasional use and up to 90 days after chronic use. However, factors like metabolism, frequency of use, and body fat percentage can affect how long it stays in your system.
I do believe after one month of smoking marijuana it will clear out of your system but I also believe it depends on how long you were smoking tge marijuana for.
