The blood stream is your body's transport system. It's used to take oxygen from your lungs and distribute it to every cell and carry Carbon Dioxide back. It also shuttles nutrients through your body, allows hormones to travel and clears toxins. The amount of time THC stays in your blood depends on a few factors. It’s important to understand how it enters your blood first.
When you smoke weed, THC, the psychoactive cannabinoid in marijuana is directly absorbed by your lungs. The inner lungs are lined with millions of these tiny airs sac's called “Alveoli”. These tiny sac's are surrounded by capillaries. The alveoli is the point of gas exchange and capillaries. These capillaries then pick up whatever is absorbed and take it into the bloodstream. Once in the blood stream, THC starts to run its course through your body and you start to feel the effects.

One of the biggest misconceptions people have with drug testing, is that tests check for THC. The truth is that they don’t. Although THC is responsible for the “high”, drug tests actually check for the presence of THC-COOH, a metabolite. Once Marijuana is smoked or eaten,THC is absorbed into your blood and then metabolised by the liver. The high only lasts until it's completely metabolised. After that, the blood carries THC-COOH throughout your system. That's when THC starts to be absorbed into fat cells, hair follicles and nails.
It’s time to really pay attention now. I’m about to tell you the key to cleansing your system and try to clear up any misconceptions you may have. First Let's go over what we learned so far:
OK, so the tricky part. THC is now trapped in fat. That means it will stay there until the fat cells are metabolised for energy. You can use this information in two ways
Get it?, I’ll explain a little better, but first one more point you have to keep in mind: Your body is always burning a little fat for short term boosts of energy
OK, I know I’m boring you with all this BS, but trust me, understanding this stuff will help you detox successfully. Let's go over a few scenarios that might help you determine how long weed is detectable in your blood, On average, a regular (more than 2x a month) pot smoker or user will have THC in their bloodstream for up to 3 months after the last time they used. But let's say you only smoke once in the post 5 to 12 months. In this case, you can expect to be clear within 3 to 5 weeks after. You can speed up detox times by burning fat. But, this is also a little tricky. If you rarely smoke weed, exercise and dieting will help. But if you have been regularly using pot, it may not help.
Successfully Detoxing your Blood So what's the biggest mistake anyone can make before a drug test, this includes urine, blood and saliva? Exercising, dieting or trying to burn fat until they get tested!
Big mistake, remember what you learned, THC is trapped in fat. Exercise, diet or whatever else you decide to do to burn fat and THC detox as soon as you can. For as long as you can, but stop a day or two before you get tested.The last thing you want is to release THC-COOH from fat the day you get screened. You should burn as much as you can days prior. Drink plenty of water to flush out your system through out, no stop.
Let me give you somewhat of a schedule for clarification, I'll make it easy to understand Let's say you have 2 weeks (14 days) to cleanse out your system. You're a casual smoker that's fairly lean, so the concentration of THC in fat cells is moderate.
Insulin triggers cell storage, lack of insulin makes you burn fat. That means stay away from carbs while you're detoxing. This will help you burn off fat. Eat carbs to spike insulin and trigger storage, a.k.a, stop burning fat.
If you're thin or have low body fat, you're in luck. The detox process will be easier because you don't have much fat for THC storage. If you're a male over 20% body fat, that's smokes on a regular basis. More time is needed to get THC out of your blood. In either case, THC is in your blood for up to 3 months if you don’t try to detox. Also, the most important things to keep in mind is; THC is stored in fat and reintroduce into the bloodstream as those fat cells are burned.
