My personal experience is if I heat the same amount of ground up flowers in my dry herb vaporizer as id normally smoke in a spliff then the effect is completely different ~DGF
The Johns Hopkins Behavioral Pharmacology Research Unit in the United States has determined that vaping is a lot stronger than smoking the same amount of cannabis. Over the course of six 8.5-hour sessions, 17 participants got highly medicated in the name of science. They were given cannabis containing 0mg, 10mg or 25mg of THC (tetrahydrocannabinol – which gives the drug its psychoactive edge) to both smoke and vape in blind tests. Each of them had smoked weed before, although not for 30 days before the test. And at the end of the experiment, they had to fill in a questionnaire and go through a bunch of physical and cognitive tests.
The results showed that when it came to 25mg, you’re going to get high as a kite regardless of whether you vape or smoke it. But the lower amount of 10mg was much more potent when it was vaped than when it was smoked.
‘Vaporized cannabis produced greater pharmacodynamic effects and higher concentrations of THC in blood compared with equal doses of smoked cannabis’
