Early and unfounded stories concerning marihuana led to many sanctions being placed on the drug. They have also brought about the requirement that the drug be proved safe beyond any reasonable doubt for any consideration to be given to removing restrictive sanctions. Some of the misinformation has been dispelled by controlled studies of its effects. Present available research does not support the thesis of permanent damage, either physical or mental. Yet there appears to be no ongoing research that will adequately demonstrate the safety or the dangers of the drug.
关于大麻的早期且毫无根据的报道导致了对该药物的诸多制裁。这些报道还带来了一项要求，即必须无可置疑地证明该药物是安全的，才会考虑解除限制性制裁。对其效果的对照研究消除了一些错误信息。目前现有的研究并不支持大麻会造成身心永久性损害这一论点。然而，似乎没有正在进行的研究能够充分证明该药物的安全性或危险性。
