Medical marijuana

The S-LAB brand carries thirty-eight of eighty-five cultivars in the Polish pharmacy list, all under two registered names. We show what this means for prescription fulfillment and how to know which strain the package contains.

The 18 percent declaration means a range from 16.2 to 19.8 percent, and the 20 percent declaration means a range from 18.0 to 22.0. These two ranges have a common segment, so a weaker and stronger label can describe the same measurement.

The number on the cannabis label is a declaration of total tetrahydrocannabinol, confirmed by measurement with an allowable difference of ten percent. We explain the difference between THC and the acid form THCA and where the conversion factor 0.877 comes from.

The declared 22 percent describes the raw material, not the patient's dose. We explain titration, organism tolerance, and why the same number means something different for a person treated for a year.

The declaration of 25 percent is a value assigned to the batch, not a measurement of the dispensed batch. We show in which potency range scientific reviews place it and what this division does not distinguish.

Flower with a declaration of 27 percent: what this number means, what systematic reviews link to higher potency of raw material, and why their results describe co-occurrence, not causation.

The boiling point is not a threshold below which terpenes stand still. We explain what really governs their evaporation from dried cannabis and why published temperature tables are not comparable.

The thirty percent declaration is currently the upper end of the pharmacy offer for flower. We explain what this number measures, why the reference point for the word strong has shifted over half a century, and what this means for reading older studies.

We checked the boiling points of eleven terpenes of this cluster in the public PubChem database. Six have pressure given, one only a measurement in nearly vacuum, two a bare number, and two have no record at all.

The number on the display describes the heating element or air, not the raw material lying in the chamber. We gather what is known about this difference and state clearly what has not been publicly measured.
