Methorphan comes in two isomeric forms, each with differing pharmacology and effects:

• Dextromethorphan - An over-the-counter cough suppressant, as well as dissociative hallucinogen.
• Levomethorphan - A potent opioid analgesic that was never clinically developed; the codeine analogue of the powerful opioid agonist analgesic levorphanol (Levo-Dromoran).

Racemethorphan refers to the racemic mixture of both of these stereoisomers. It is listed under the Single Convention on Narcotic Drugs 1961 and is therefore listed in the United States as a Controlled Substance, specifically as a Narcotic in Schedule II with an ACSCN of 9732 and an annual aggregate manufacturing quota of 3 grammes in 2014. The salts in use are the hydrobromide (free base conversion ratio 0.770) and the tartrate (0.644)

Column-generating template families

The templates listed here are not interchangeable. For example, using {{col-float}} with {{col-end}} instead of {{col-float-end}} would leave a <div>...</div> open, potentially harming any subsequent formatting.

Column templates

Type	Family	Handles wiki  table code?†	Responsive/ Mobile suited	Start template	Column divider	End template
Float	"col-float"	Yes	Yes	{{col-float}}	{{col-float-break}}	{{col-float-end}}
	"columns-start"	Yes	Yes	{{columns-start}}	{{column}}	{{columns-end}}
Columns	"div col"	Yes	Yes	{{div col}}	–	{{div col end}}
	"columns-list"	No	Yes	{{columns-list}} (wraps div col)	–	–
Flexbox	"flex columns"	No	Yes	{{flex columns}}	–	–
Table	"col"	Yes	No	{{col-begin}}, {{col-begin-fixed}} or {{col-begin-small}}	{{col-break}} or {{col-2}} .. {{col-5}}	{{col-end}}

^† Can template handle the basic wiki markup {| | || |- |} used to create tables? If not, special templates that produce these elements (such as {{(!}}, {{!}}, {{!!}}, {{!-}}, {{!)}})—or HTML tags (<table>...</table>, <tr>...</tr>, etc.)—need to be used instead.
