It’s not uncommon for cannabis users—especially long-term ones—to wonder: “Why do I feel high when I haven’t smoked?” For some, the sensation of being high can return days or even weeks after their last session. While rare, this phenomenon has sparked curiosity about whether THC stored in fat cells could be the cause.
Let’s dive into what science has uncovered so far about cannabis flashbacks, THC release, and how your body handles stored cannabinoids over time.
Can You Get High Without Smoking Weed?
We’ve all heard stories of LSD flashbacks, but what about cannabis flashbacks? While less common, some chronic cannabis users claim to feel high even after abstaining for weeks or months. It might sound strange, but anecdotal evidence suggests it’s possible under certain conditions.
So what’s really happening here? To answer that, we need to look at how THC, the psychoactive compound in weed, interacts with your body—particularly your fat cells.
What Is THC and How Does It Work?
Δ9-tetrahydrocannabinol (THC) is the primary psychoactive compound in marijuana. It binds with CB1 receptors in the brain, mimicking the body’s natural endocannabinoid, anandamide. While the high from THC wears off within a few hours, the compound itself can linger in your system for much longer.
This is because THC is fat-soluble, meaning it gets stored in fat cells, especially with repeated use. Even when you're no longer feeling the effects, traces of THC can stay in your body for days, weeks, or even longer.
How Long Does THC Stay in Your Body?
Just because the high is gone doesn’t mean your body is THC-free. In fact, most weed drug tests don’t even look for THC directly—they detect THC-COOH, a non-psychoactive metabolite produced by your liver after smoking weed or consuming cannabis.
-
Urine tests: Can detect THC metabolites up to 6 weeks or more in heavy cannabis users.
-
Blood tests: Can find active THC in the bloodstream for up to a week.
So even though the effects of weed might have worn off, the evidence of use—and perhaps the potential for renewed effects—can linger for quite a while.
Why You Might Feel High Without Smoking
Here’s the theory: If THC is stored in fat, then activities that burn fat—like exercise or fasting—might release some of that THC back into the bloodstream, possibly triggering a renewed feeling of being high.
But does this actually happen? Let’s look at what research has found.
Scientific Studies on THC Release from Fat Cells
1. Fasting and THC Release in Rats
In a 2014 study, rats were given THC for five days, then fasted for 24 hours after a short break. The fasted rats showed higher levels of THC in plasma and changes in behavior compared to the non-fasted group. This suggests that fasting may cause THC stored in fat to re-enter the bloodstream, possibly resulting in mild psychoactive effects.
2. Exercise and THC Levels in Humans
Another study looked at regular cannabis users who exercised for 35 minutes either after eating or fasting. Both groups saw increased levels of THC in blood plasma, showing that exercise can release stored THC. However, no one reported feeling high, and behavioral effects weren’t measured.
3. A Conflicting Study: No Changes in THC Levels
A separate study found no increase in THC blood levels after fasting or exercise in chronic cannabis users undergoing detox. This challenges the idea that stored cannabis compounds can always be re-released in meaningful amounts.
So... Can THC in Fat Cells Make You High Again?
Unfortunately, there’s no clear answer—yet. While we know that THC is stored in body fat, and that exercise or fasting can raise THC plasma levels, the increase might be too small to cause a noticeable high.
Other factors could also play a role. Chronic cannabis use can cause lasting changes in the brain, especially if use began during adolescence. This could contribute to feeling high when you haven’t smoked, even if THC levels in the body are low.
Does This Happen to Everyone?
Not at all. Most people don’t experience cannabis flashbacks, even with heavy use. But for a select few—especially long-term stoners—it’s not unheard of. Fortunately, most anecdotal reports suggest these sensations fade over time with continued abstinence.
Final Thoughts: THC, Fat, and Flashbacks
To sum it up:
-
THC is stored in fat cells, especially in chronic cannabis users.
-
Exercise or fasting may release stored THC, potentially increasing THC levels in blood plasma.
-
Whether that causes you to feel high without smoking is still uncertain and likely varies from person to person.
If you’ve recently quit smoking weed and are still feeling high, rest assured it’s probably temporary.
