<s>[INST] A research team is conducting a study on the effects of using a specific medication used to treat patients with high blood pressure. They found that 1 out of 10 patients experienced a drop in blood pressure within one hour after taking the medication. Later in the study, they noticed that 7 out of 10 patients with high blood pressure within that group reported a significant drop in blood pressure after 2 weeks of regular use. 

If 80 patients participated in this study, how many patients in total experienced the beneficial effect of the medication (a drop in blood pressure) at both stages of the study?[/INST]
