Thats exactly right, pure high grade heroin is extremely safe as long as you don't OD of course. Its very natural and easy going on the body both mentally and physically, you get a really nice clean high and generally the next day you feel fine. You have no hang-over like cheap booze gives. There's so many people that lead normal lifes that use H everynight to chill out, you wouldn't pick them out aye cause they don't let themselves go.
Even codeine will chill you out, it converts in the liver too morphine at a ratio of 10%.
