In a large online survey of 23,500 New Zealanders who used cannabis and at least one other substance in the same six-month period, substantial proportions reported that cannabis use led them to use less alcohol (60%), synthetic cannabinoids (60%), morphine (44%), and methamphetamine (40%). About seven out of ten said cannabis had no impact on their use of LSD, MDMA, or cocaine. One in five reported that cannabis led to more tobacco use. Co-use patterns varied by age, ethnicity, and lifestyle: young adults (21–35) were more likely to report reduced drinking and methamphetamine use, while Māori were more likely to report reduced use of alcohol, tobacco, methamphetamine, and LSD.
