Au contraire, mon freir.
Contrary to safrole and anisole, myristicin and--to a lesser extent--elemicin are psychoactive in their own right.
Trust me, drink a 4oz bottle of 8 to 9% pure myrisiticin ("essential oil of nutmeg") and you won't need rabbit liver aminases to feel a buzz for several weeks or months afterwards even.
You see, I never invoked the debunked rabbit liver amination myth. However, I didn't need to because widespread anecdotal evidence makes it plain enough to see that even nutmeg powder possesses mild to moderate hallucinogenic acitivity, sometimes bordering on the bizarre, when ingested in sufficient quantities.
For example, ever since that time (10 years ago) I have had colored photographic memory flashes of images on demand inside my mind, and needless to say, was quite loony for a time afterwards.
That being said, around the same time, I did run across some green 80 to 100mg MMDA pills, and that experience was even more electrifying. All in all, the amphetamine adduct of myristicin is to be much preferred to the essential oil ingestion route, although the after effects of the latter last much longer than those of the former.
Hope that helps. As for Shulgin's claim that 100mg MDA, 100mg MMDA, and 100mg TMA was indeed quite a "sparkly" combination, well, we can only take his word for it (or not) as is printed in PiHKAL, and I--for one--am a firm believer.
