Currently, the current body of scientific evidence suggests that terpenes do not have an adverse long-term effect at normal, everyday exposure levels. The primary risk associated with terpenes is through the repeated inhalation of very high concentration levels (above 6-8%) or contaminants. Therefore, long-term results of using terpenes are more likely to depend on how often and how much a person uses cannabis, rather than on the use of terpenes alone.
