The use of Cannabis sativa is on the increase worldwide especially among adolescents and youths. This study investigated the effect of cannabis smoking on renal functions in young and apparently healthy male students of Nnamdi Azikiwe University, Nnewi campus, Anambra state, Nigeria. A total of 60 male (40 cannabis smokers and 20 controls) subjects participated in this study. A well-structured questionnaire was used to obtain the demographic data and anthropometric of subjects. Thereafter, 5mls of fasting blood sample was collected from the subjects into plain container for the estimation of biochemical parameters (creatinine, urea, uric acid, electrolytes). Renal parameters were estimated using standard methods. Data obtained were statistically analyzed using paired student t-test and pearson r correlation. Result showed that the mean serum levels of urea, creatinine, K+, Na+, Cl-, ionized calcium, total calcium, total carbon dioxide, anion gap, and pH were not significantly different in both smokers and control subjects(p>0.05). However, there was significantly higher mean serum level of uric acid (2.42 ± 38.54 vs 1.92 ± 41.61; p<0.05) and total calcium (16.0 ± 0.30 vs 10.24 ± 0.18; p<0.05) in smokers compared with control subjects. Again, BMI was significantly higher in smokers compared with non-smokers (23.96 ± 3.15; p<0.05 Vs 21.95 ± 2.17; p<0.05). Therefore, cannabis use had no deleterious effect on the kidneys, but the significantly higher uric acid levels in the smokers may provide some anti-oxidant protection. However, further studies are necessary to further unravel the full potentials of cannabis use.

Land degradation is a global negative environmental process that causes the decline in the productivity of land resources’ capacity to perform their functions. Though soil and water conservation (SWC) technologies have been adopted in Geshy subcatchment, their effects on soil quality were limitedly studied. The study was conducted to evaluate the effects SWC measures on soil quality indicators in Geshy subcatchment, Gojeb River Catchment, Ethiopia. A total of 54 soil samples (two treatments–farmlands with and without SWC measures ∗ three slope classes ∗ three terrace positions ∗ three replications) were collected at a depth of 20 cm. Statistical differences in soil quality indicators were analyzed using multivariate analysis of variance (ANOVA) following the general linear model procedure of SPSS Version 20.0 for Windows. Means that exhibited significant differences were compared using Tukey’s honest significance difference at 5% probability level. The studied soils are characterized by low bulk density, slightly acidic with clay and clay loam texture. The results revealed that farmlands with SWC measures had significantly improved soil physical (silt and clay fractions, and volumetric soil water content (VSWC)) and chemical (pH, SOC, TN, C : N ratio, and Av. phosphorus) quality indicators as compared with farmlands without SWC measures. The significantly higher VSWC, clay, SOC, TN, C : N ratio, and Av. P at the bottom slope classes and terrace positions could be attributed to the erosion reduction and deposition effects of SWC measures. Generally, the status of the studied soils is low in SOC contents, TN, C : N ratio, and Av. P (deficient). Thus, integral use of both physical and biological SWC options and agronomic interventions would have paramount importance in improving soil quality for better agricultural production and productivity.
