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.
Change your encryption to WPA. WPA uses either a passphrase (a shared secret) that is comprised of 8 to 63 characters or a fixed-length of 64 HEX characters. Oh ... if your network card and/or router does not support WPA (doubt it though since it became available in 2003) you need to buy new hardware.
