I have seen this issue with a lot of things. It's hard to get a hold of good stump remover because KNO3 can be used in explosives (It is also useful for simple harmless chem experiments like making smoke bombs). Can't get a hold of syringes with needles easily because druggies will use them. The list goes on. The worst part is, those with nefarious plans will still find a way while we with legitimate interests are inconvenienced and harassed. It's sad and doesn't seem like something that will ever change because there are people who see us as dangerous wackos because they don't understand what we're doing.

1-(3-Methylbut-2-enyl)guanidine Hemisulfate 1 (Galegine) and General Procedure for Synthesis of Guanidine Hemisulfates.A mixture of 4-bromo-2-methyl-2-butene (19.4 g, 1.0 equiv, 130 mmol) and potassium phthalimide (29.8 g, 1.2 equiv, 161 mmol) were suspended in DMF (200 mL) and stirred at 120 C for 1 h before heating to 160 C and stirring for a further 18 h. The mixture was poured over ice and washed with dichloroethane (5 × 50 mL), and the organic phases were separated and combined before washing with sodium hydroxide solution (0.1 N) (2 × 100 mL) and water (2 × 50 mL). The organic extracts were separated, dried over anhydrous magnesium sulfate, filtered, and concentrated to leave a crude solid that was crystallized from cold ethanol to give the intermediate 2-(3-methylbut-2-enyl)isoindoline-1,3-dione (25.6 g, 93%) as a white solid; mp 100-101C
A mixture of 2-(3-methylbut-2-enyl)isoindoline-1,3-dione (10 g, 1.0 equiv, 46.6 mmol), ethanol (100 mL), and hydrazine hydrate (85%) (2.9 mL, 1.2 equiv, 51.1 mmol) were stirred under reflux for 1 h, cooled, hydrochloric acid (1M) (5.2 mL, 1.2 equiv, 51.1 mmol) added, and then refluxed for a further 1 h. The mixture was allowed to cool, filtered, and the residue washed with cold water (100 mL) before reducing the filtrate under vacuum to give the intermediate 3-methylbut-2-en-1-amine hydrochloride (4.4 g, 78%) as a white solid; mp 95-97C2-Methylthiopseudourea sulfate (6.95 g, 1.0 equiv, 150 mmol) and 3-methylbut-2-en-1-amine (9.1 g, 2.0 equiv, 100 mmol) were dissolved in water (100 mL) and ethanol (100 mL). The mixture was stirred at reflux for 18 h, connected to a series of bleach traps, before cooling and reducing under vacuum to give a white crude solid. The compound was suspended in water (30 mL) and heated until it barely dissolved before allowing to slowly cool upon which a white solid began to form. After allowing the formation of the solid to continue overnight, it was collected by filtration and dried in the oven to give the title compound (5.4 g, 62%) as a white solid; mp 216-218C

From a point of view of materials and time it is not costly to set up a home
laboratory for the purposes of synthesizing chemical compounds or even
perform simple procedures in biotechnology - raising bacteria, assaying
genes in lower animals, and so on. It is, however, illegal to just forge
ahead and do this in most US states or in much of Europe due to the many
prosaic, stupid laws that encrust the body politic....
It is in fact the drug war, and not the normal background levelprotectionism of licenses and zoning, that turns DIYbio, amateur chemistryand other similar citizen science activities into an expensive and riskyendeavor.
I'm not trying to be discouraging- I am trying to encourage people to be realistic, and talk in terms of what they want to accomplish. Once we know that, then we can work on removing the real barriers to making that happen.

For example, in Texas, you cannot sell or manufacture for sale drugs without a license, just like you cannot sell food without a license. http://www.dshs.state.tx.us/fdlicense/links.shtm But you don't need a license to cook food for yourself and anyone else in your home, you just can't open a business and sell it. Likewise, you don't need a permit to buy most chemicals. It is not illegal to buy either bleach or ammonia, for example- you can do so at any corner store. It's not even illegal for you to mix them without a permit. It is however illegal to mix them in significant quantities and spew the fumes out into the air- it's called attempted murder and pollution of the environment with a deadly poison.
