I mean &quot;types&quot; more like I might say &quot;types of water&quot;.  Sure, there&#x27;s only <i>one</i> real water, and whether there&#x27;s lemon added, or if it&#x27;s filtered through limestone, it technically bears a different configuration (now making it water with lemon, or water with limestone).<p>That said, LSD is (to my experience) rarely concocted at pharmaceutical grade. Different concentrations, different configurations, different additives lead to different outputs, each of which we might all refer to as LSD colloquially, but which are all effectively &quot;water, with a hint of lemon&quot;, or whatever else, moreso than LSD-25 vs. something else.
