In the P.D. era (that is, Pre-D.R.U.I.D.), there wasn’t any way to tell, just a subjective experience. Trying to remember and compare how stoned you got from the marijuana you smoked yesterday, and trying to compare that to how stoned you are today from a different batch, can be very difficult. But with D.R.U.I.D., you can now create a D.R.U.I.D. Time Profile of different strains of marijuana and compare the different effects. Also, different strains of marijuana can react differently to different temperature settings on the Volcano.

As you can see, two different bags of the same strain (Sativarin-A), but with different Volcano temperature settings, produced very different levels and duration of highs.
