The symptom of cannabis craving also yielded strong evidence for linkage on chromosome 3 between 164 and 176 cM with a peak at 171 cM (LOD = 4.4). There was additional evidence for linkage for cannabis craving on chromosome 1 between 36 and 48 cM with a peak at 43 cM (LOD = 3.6), and on chromosome 6 between 195 an 202 cM with a peak at 202 cM (LOD = 3.2). There was suggestive evidence on chromosome 9 between 25 an 44 cM with a peak at 35 cM (LOD = 2.6), and on chromosome 15 between 75 and 84 cM with a peak at 81 cM (LOD = 2.3).
