>>1558237>or are there actual risks involved with reusing bottles such as these?If such risks existed, they would be present for the initial use
And there are risks on using plastic bottles. Flexible plastics will shed microscopic plastic particles into he liquid inside them. You could buy metal bottles, but all metal bottles in current year will have some sort of plastic internal coating, which will shed microscopic particles quickly if the metal is dented/flexed at all
But as I write this, I'm currently using two used Gatorade bottles as water bottles
