Moulded tablets

Small numbers of tablets may be made by moulding, a similar process to that once used in pharmacies. The active ingredient, a diluent and some form of binder (gum or adhesive) are pressed into a mould and allowed to set. Perforated metal sheet or even pegboard may be used as the mould. This dose form was common for lysergic acid diethylamide (lysergide, LSD) in the UK in the 1970s. Small ‘microdots’ (2.4 mm in diameter and 1.3 mm thick, weighing 5 mg: Fig. 1) were produced in large numbers using sheets of perforated metal.

The product shown in Figure 2 is from a London club’s ‘amnesty bin’. The tablet is made from plaster-of-Paris to resemble an ecstasy tablet, but it contains no active ingredients.
