Can a cigarette filters lock THC?

Cigarette filters are primarily designed to reduce harmful tar and particulate matter from tobacco smoke, not to selectively lock or capture THC (tetrahydrocannabinol), the psychoactive component of cannabis. While some studies suggest that filters may absorb small amounts of THC, they are not effective in completely retaining it. Therefore, smoking cannabis through a cigarette filter may still result in significant THC loss, ultimately reducing the potency of the inhaled smoke.
