    What exactly does Delta 9 mean? I know the structure for THC is Delta-9-Tetrahydrocanninbol*(sp?) but what does that exactly infer? :cool:

    It's a scientic term used to describe hydrocarbons. I can't really get much more in depth than that, cause I don't know!

    Maybe this will help you...:)

    RATIONALE. Although smoked marijuana contains at least 60 cannabinoids, Delta(9)-tetrahydrocannabinol (Delta(9)-THC) is presumed to be the cannabinoid primarily responsible for many marijuana-related effects, including increased food intake and subjective effects. Yet, there has been no systematic comparison of repeated doses of oral Delta(9)-THC with repeated doses of smoked marijuana in the same individuals. OBJECTIVE. To compare the effects of oral Delta(9)-THC and smoked marijuana in humans under controlled laboratory conditions. METHODS. Eleven healthy research volunteers, who reported smoking an average of six marijuana cigarettes per day, completed an 18-day residential study. Marijuana cigarettes (3.1% Delta(9)-THC, q.i.d.) were smoked or Delta(9)-THC (20 mg, q.i.d.) was taken orally using a staggered, double-blind, double-dummy procedure for three consecutive days. Four days of placebo administration separated each active drug condition. Psychomotor task performance, subjective effects, and food intake were measured throughout the day. RESULTS. Relative to placebo baseline, oral Delta(9)-THC and smoked marijuana produced similar subjective-effect ratings (e.g., "high" and "mellow"), although some effects of smoked marijuana were more pronounced and less prone to the development of tolerance. Additionally, participants reported "negative" subjective effects (e.g., "irritable" and "miserable") during the days after smoking marijuana but not after oral Delta(9)-THC. Both drugs increased food intake for 3 days of drug administration, but had little effect on psychomotor performance. CONCLUSION. These results indicate that the behavioral profile of effects of smoked marijuana (3.1% Delta(9)-THC) is similar to the effects of oral Delta(9)-THC (20 mg), with some subtle differences.

    Sounds about right to me...

    i know a bit about chemistry. organic molecules can have different structures with the same composition. delta 9 simply refers to the structure. im not so sure about it but i think delta 9 is where the tetrahydro joins onto cannabinol.

    ...anyone else survive Organic Chem?

    wanna see a picture of
    THC molecules ?

    Here is an explanation of what delta-9 means written by Delta-9 Technologies, LLC, an indpendent cannabis laboratory accredited with the Association of California Cannabis Laboratories. I am the owner and earned my Ph.D. in organic chemistry. Although you need some chemistry knowledge to understand the details, I attempted to present the material in an understandable way.
