Smoking is a bad habit that has harmful effects on health, and one of its most important components responsible for addiction is nicotine, which is dangerous to health in general and to genetic material in particular, as it causes genetic changes and leads to diseases that can be inherited across generations. Among these changes is the occurrence of a genetic mutation in the OPRM1 gene. This gene gives instructions for making a protein called opioid receptors, “which is considered the internal body system that causes addiction.” Materials and methods: 22 samples were collected, and all the cases were male, ages ranging from 15 to 40 years. Most of them had smoked early age. The DNA genetic material was extracted from the samples using the QIGEN Kit, and the concentration of the extracted genetic material was measured and transferred onto a gel, then a polymerase chain reaction (PCR) was performed after designing the appropriate primer to replicat.

This research was carried out for the purpose of studying the effect of fertilization with different concentrations (0, 5, 10, 15, 20 g/kg soil weight) of olive leaf waste on the growth of pepper plants. Capsicum annuum L. cultivar PEPERNE. Growth parameters which were used as an indicator of the response of pepper plants to fertilization treatment which are: the number of leaves, total plant length, relative dry weight, leaf area, and total chlorophyll content, The content of olive leaf residues of some mineral elements, which are: nitrogen (N), phosphorus (P), Potassium (K) and iron (Fe). was also estimated. The results showed that fertilization with olive leaf residues had a positive effect on most of the growth parameters used. It turned out that olive leaf residues contains some mineral elements that are nutritious for the plant, which contributed to improving the growth of pepper plants. .
