The good news is that, unless an animal is confined in a pillowcase (as above) or in a room with extreme amounts of smoke, inhaling secondhand marijuana smoke is not likely to lead to intoxication. If this were a concern, it would be hard to walk the streets of San Francisco without catching a secondhand buzz.
If you have a message with multiple segments (a message over 160 characters will be broken up into 160-character segments), Twilio will queue the messages and release them at the rate of one message segment per second.
Technically, you can-if your domain register allows you to (they can have their limitations on the length of the name). Generally there can be up to 127 labels (parts separated by dots), each label up to 63 charaters. However the whole name cannot exceed 255 characters. In your example first label is 31 characters, second - 27, third - 29, fourth (tld) - 3 charaters. Which makes 93 total. Which is (theoretically) OK.
