Hvis man nærlæser
originalartiklen fra videnskab.dk ser man at det kræftfremkaldende stof, der er tale om er acetaldehyd. Så vidt jeg er orienteret findes det i masser af planter, så, som Booty-Lone nævner, er det altså et spørgsmål om at man ryger plantemateriale, ikke specifikt at man ryger hash.
Derudover bliver jeg nødt til igen at nævne mit had til enhver journalist, som ikke kan finde ud af at give en ordentlig henvisning til sine kilder.
DET ER ET ENESTE LILLE BITTE LINK. ER DET VIRKELIGT SÅ SVÆRT?
EDIT:
Jeg kiggede lige lidt omkring og faldt over denne artikel:

Hypothesizing that Marijuana Smokers are at a Significantly Lower Risk of Carcinogenicity Relative to Tobacco-Non-Marijuana Smokers: Evidenced Based on Statistical Reevaluation of Current Literature, Chen, Amanda L. C. et al.
JOURNAL OF PSYCHOACTIVE DRUGS, 2008, Vol. 40 (3), p. 263-272
Abstract: A hypothetical link between marijuana smoking and cancer has been established based on a number of misleading assumptions. However, recent studies tend to suggest, if anything, an inverse association between marijuana use and cancers. To test the hypothesis that marijuana smoking significantly lowers the risk of developing cancer in humans, we analyzed published data from a prospective cohort study on cancer incidence among nonsmokers (NS), marijuana-only smokers (MS), tobacco-only smokers (TS), and marijuana and tobacco smokers (MTS). Using the log linear model to calculate the probability of developing each cancer form as a function of the interaction between marijuana and tobacco smoking, as well as functions of marijuana and tobacco smoking main effects whereby chi square statistics were calculated for the interaction and main effect estimates, we found that in all cases tested there was a significantly lower risk for MS compared to TS. Male and female TS had a greater probability of developing lung cancer than did MS. Males and females TS had a greater probability of developing lung cancer compared with NS. Males and female MTS had a slightly higher probability of developing lung cancer than did MS. This difference was statistically significant: chi 2 = 30.51, p <.00001, with a correlation coefficient of -0.75, Z = -7.84, p <.05. Male and female MTS had a lower probability of developing lung cancer than did TS. This difference was statistically significant: x 2 = 71.61, P =.00003, with a correlation coefficient of 0.61, Z = 5.06, p <.05.
Det ser jo meget godt ud, men desværre kan jeg ikke få adgang til den fulde artikel. Hvis der er nogen, der har mulighed for det, ville jeg blive helt latterligt glad i hovedet.
Min pointe med det er, at selv hvis man i laboratoriet beviser, at hash skulle være kræftfremkaldende, så ser det ikke ud til at det rent faktisk sker i virkeligheden. Hvis denne artikel holder hvad den lover, kan man jo nemt afvise ethvert teoretisk studie.
