To analyze the current situation of Colombian regulation, it is necessary to compare some specific aspects with the legislation used in other countries where the UAVs topic dates to many years ago. This study is focused on evaluating all the possibilities to make the Colombian regulation effective without closing opportunities of research and development growth, but still guarantee the privacy and intimacy rights of the population. Results from our study are currently being used in the development of the Colombian regulation and they are proven useful to instigate informative debates and identify areas where specific needs are to be address in Colombia.

<i>Objective:</i> To investigate the association between four polymorphisms of the 5-HT_2A receptor and 5-HT transporter genes and heroin dependence. <i>Methods:</i> 113 heroin- dependent patients (DSM-IV criteria) and 420 unrelated healthy controls from Asturias (Northern Spain) were genotyped using standard methods. <i>Results:</i> There was an apparent difference in the distribution of genotypes for A-1438G polymorphisms (p = 0.024, not significant after Bonferroni correction). The 5-HT_2A -1438A allele was significantly more common in patients than controls [0.55 and 0.45, respectively; corrected p = 0.042, OR = 1.51 (95% CI = 1.13–2.03)]. An interaction was observed between A-1438G of 5-HT_2A and 5-HTT polymorphisms. The association between the -1438AA vs. AG/GG genotypes and heroin dependence was enhanced in the presence of 12-repeat 5-HTT VNTR and short 5-HTTLPR alleles [24.8% in heroin-dependent patients vs. 12.6% in controls; corrected p = 0.045, OR = 2.28 (95% CI = 1.36–3.82)]. <i>Conclusions:</i> Our findings support a contribution of the 5-HT_2A gene to susceptibility to heroin dependence, as well as a possible synergistic effect of 5-HT_2A and 5-HTT genes on susceptibility to heroin dependence.
