The possibility was examined in a literature review, if smoking (including marijuana/cannabis/hashis) could have any benificial effect on MS. The border condition on lawfulness is met when MS-patients start smoking the latter mentioned substances. The review proved to be most surveyable (only 25 references on MS, human and (marijuana smoking or smoking) 1966-99. Mostly, these are referred below
The effects of cannabis have been described as antispasmotic and analgesic. This does not explain all possible effects in MS. One way of action, independant of a definite drug effect, could simply be in forcing the patients to a more quiet state while smoking than would otherwise be the case. However, no such indication were found in the study. Being forbidden as „soft narcotic drug,“ marijuana is a spectacular option . Consroe et al.  identified 112 MS-patients who reported a benificial action when they smoke marijuana. The value of it could be caused by a subjective well-being by an objective deterioration not noticed by the patients. Greenberg et al.  found that „smoking one marijuana cigarette ... further impairs posture and balance in patients with spastic MS.“ In apparent contrast, but possibly also explained by a relaxing effect, Schon et al.  found that it caused a suppression of the nystagmus, often seen in MS.
Otherwise, this review did not present any good news for
tabacco smokers among MS-patients. In analogy with the study of Greenberg
al. , Emre and de Decker  found that „nicotine causes a transient
worsening of motor functions ..., which can be due to its effects
on the central nervous system or vegetative-vascular functions.“ Ammenheuser
al.  found that the mean pre-treatment variant frequencies
of the MS patients who were cigarette smokers was more than four times
higher than the same variable of the 4 MS patients who were non-smokers.
Villard and Vessey  even concluded that „smoking may be a risk
factor for developing MS.“ Also older publications of the relationship
between MS and smoking do not favour its use [8-11].
