International terrorism and traffic in narcotic drugs would seem at first sight to represent two categories of offences that ought to be kept apart in a discussion concerning the problems of extradition in respect of them. The prima facie approach of differentiating, for extradition purposes, between international terrorism, on the one hand, and traffic in narcotic drugs, on the other hand, would appear to be warranted by the different perception of these two groups of offences prevailing in the mind of the general public. While crimes of international terrorism are perceived as being normally inspired by political motives, traffic in narcotic drugs is generally believed to be motivated solely by the prospects of quick enrichment. Since extradition treaties almost invariably exclude political crimes from their scope of application, the distinction, for extradition purposes, between terrorism and drug crimes is not far to seek.
However, these different perceptions of the two categories of crimes are somewhat deceptive, and more apparent than real, and the differences between them are, at most, differences of degree rather than of substance.
