High-THC cannabis concentrates boost levels of THC in the blood more than smoking cannabis flower, but they don’t necessarily produce a stronger “high,” a new study says. The use of concentrates produced significantly higher levels of THC in blood plasma, the study found, yet participants who consumed cannabis flower and those who consumed cannabis concentrates “showed similar neurobehavioral patterns after acute cannabis use.” A range of short-term measures of impairment did not change with the strength of the cannabis consumed.
