>>96705>Will this lead to adverse consequences?Yes, it might. These
>>96997>>97021 are probably incorrect depending on what plastic your bottles are made of. Check their bottom, the material they are made from usually is molded in a little triangle. PP or PE (for polypropylene and polyethylene) should be fine. These are the thermoplasts most reusable foodgrade containers are made from. However, for soda-bottles and the likes PET gets used a lot. This essentially is PE (polyethylene) with phthalates added to make it more shiny and transparent, most notably terephtalate; hence the 'T' in PET. Phtalates leach easily from plastics they are used in, especially into fatty liquids (butter, oils, milk,..)
Phthalates are not your friend, toxic in fact. I would not be surprised if they would become the asbestos of our generation in a decade or so, along with the bisphenols. Standard PET's status as a foodgrade plastic is being questioned more and more. Most of this information can simply be found on the wiki-page.(

PET-bottles are great for recycling, not for re-using. I know those bottle-gardens you see on pinterest sure are pretty, but be an informed pragmatist and not a eco-hipster
