how long does marijuana stay in your system after smoking a joint
Hi Jared. How long marijuana will remain in your system depends on how often or how much marijuana youâve been smoking. Other regular smokers have scored positive on the drug tests even after 45 days since last use, while some heavy smokers had marijuana show up on their tests results 90 days after quitting.i RJ. Yes, you should be OK for one time ingestion of marijuana 10 days before a drug screen. In other words, THC is usually detectable for 3-4 days after one time useâ¦.and 10 days after you eat marijuana is a long enough time for THC to clear the system.
